Description
The housings of the ME-IO 18,8... product range consist of
a 18.8 mm wide lower housing part with space for the PCB
assembly.
The lower housing part can be combined with various housing covers. The lower housing part is subdivided into 9 units
(1 Unit = 11 mm). These units can be combined with connectors and housing covers in various ways.
The housings can be snapped onto an NS 35 DIN rail.
It is possible to use the housings with a DIN rail connector
by means of which communication can be established between the housings, or the supply voltage can be transmitted.
The connectors correspond to a unit and have a push-in
connection. There are 4-pos. connectors for conductor
cross sections of up to 2.5 mm2, and 6-pos. connectors for
conductor cross sections of up to 1.5 mm2. Partially assembled or TWIN variants are also available. All in all, the 4-pos.
connectors allow for a maximum of 36 positions in a single
housing. The 6-pos. connectors even allow for up to 54 positions. As a counter-part to the connectors, there are headers in 2 or 3 unit versions for soldering onto the PCB.
The housing covers in 2 to 7 unit versions are especially
suited for installing connection systems such as USB or
D-SUB as well as display and operating elements. We
would be glad to install the required openings for you.
The 3D housing data can be found at phoenixcontact.net/products.
Make sure you always use the latest documentation.

The orange lever of the Lock and Release system is used for
locking and unlocking the push-in connectors.
The push-in connectors are available in three variants, fully
and partially assembled, and as a TWIN connector, on
which two positions are each bridged together.
The counter-part to the push-in connectors are the headers.
The housing can be optionally combined with a DIN rail connector by means of which data or the power supply can be
transmitted from module to module.

5.3
Concatenating headers
The headers must be concatenated in a way that makes it
possible to attach the Lock and Release system, which is
available in different lengths (3U – 9U).
Possible positions of 3U headers
The headers have guide pins, which have to fit into the recesses of the Lock and Release system.
Figure 6
Possible position and combination of
HSCH ...-3U... 3U headers
In Figure 6 the possible positions of the 3U headers are displayed. It shows that a direct concatenation of 3U headers
is not possible.

In front of the 3U headers it is possible to concatenate 2U
headers; housing covers are equipped before and between
them.

Guide pin and Lock and Release system
The housing is designed for 9 units. The headers can only
be concatenated at certain positions. In doing so, it is important to pay attention to the combination of the headers so
that the guide pins fit into the Lock and Release system.
It is therefore not possible to concatenate the 3U headers directly because the guide pins will then no longer fit into the
Lock and Release system. For the same reason, 2U headers must always be placed in front of the 3U headers, e.g.
the 2U on position 1 + 2 and the 3U header on positions
3 - 5.
Figure 7
Possible positions and combinations of
HSCH ...-2U... 2U headers
The 2U headers can also be directly concatenated. Figure 7
shows all possible positions. You can use the different variants of the 2U header for this purpose.
3U headers fit to some extent on the unoccupied positions
behind the 2U headers (see Figure 5 and Figure 6). In addition, housing covers can be equipped. When doing so,
make sure that there are no 1U housing covers.
In addition to the headers, housing covers can also be
equipped, which are available in 2 to 7 unit versions. Their
position can be chosen freely.

Housing cover ME-IO 18.8 C 3U S1 7035
The housing cover ME-IO 18.8 C 3U S1 7035 is used for
covering a unit of the header. The snap-in hook is therefore
positioned at an offset of 1 unit. At the position to be covered
there are no connectors in the header.
The cover can however also be used for all other headers.

To enable faster PCB removal, the hole on the

to remove the base latch before removal (see

PCB with FE contact
The FE contact establishes the contact between the electronics module and the DIN rail in order to discharge electromagnetic interference.
The lower housing part is delivered with a pre-assembled
FE contact. A pad has to be equipped on the PCB for this
purpose (FE contact pad with tin surface; Sn 2-4μm).

DIN rail connector
It is possible to combine the housings with a DIN rail connector (TBUS) by means of which data or the power supply
can be transmitted from module to module.
The DIN rail connector is simply laid into the DIN rail
NS 35/7.5 and the housing is snapped onto it.
This concept allows complete individual devices to be removed from the group without interrupting the contact chain.
In addition, the DIN rail connector is compatible with the
ME-MAX and ME-TBUS housing ranges.

Assembling the Lock and Release system
9.2
Inserting the PCB
When the PCB is completely assembled, the orange Lock
and Release system, included in the scope of delivery of the
lower housing part, has to be assembled.
Pay attention to the positioning of the connectors
and the headers (see page 6).
To do this, proceed as follows:
• Solder the header onto the PCB.
Figure 41
•
Attaching the Lock and Release system
Attach the orange Lock and Release system onto the
header. The recesses of the Lock and Release system
have to fit over the protruding guide pins of the header.
Press the Lock and Release system against the header.
Figure 43
•
Figure 42
•
Inserting the PCB
Insert the PCB into the guide slot of the housing and
push it downwards until it audibly snaps in.
Attaching the spring
Attach the spring which is included in the scope of delivery. The spring is inserted at one of the possible positions.

Figure 44
•
Attaching the housing cover
Attach the housing covers if they are equipped.
The housing cover has two snap-in hooks on one side
and only one on the other side. The side with the two
snap-in hooks has to be facing the base latch.
Make sure that the concealed side guides are also
snapped in. To do so, it helps if you lightly push the
sides of the housing together.

WARNING: Electric shock
Make sure that the module is free of current.

•
Insert a screwdriver through the opening of the Lock
and Release system.
Hook the tip of the screwdriver into the base latch.
Pull the screwdriver forward to release the Lock and
Release system.
The connectors are lifted and the contact is released.
But the connectors do not fall out.
The housing cover remains in its position.
You can code the connectors and the headers in order to
prevent them from being connected incorrectly by accident.
Each connector has for four or five positions for attaching
coding plates.
Use the coding profile CP-DMC 1,5-THR NAT, 1790647.
• Insert a coding plate at the correct position and twist it
off the pentagonal holder.

Mounting the housing on a DIN rail
Conductor cross section 1.5 mm² ... 2.5 mm², solid or

• Insert the stripped wire into the round opening of the terminal block without using a tool.
Wires with a smaller cross section or stranded conductors without ferrule
• Push in the pushbutton with a screwdriver to open the
spring.
Disconnecting
• Push in the pushbutton with a screwdriver to release.
• Pull out the conductor.
We recommend using a bladed screwdriver
SZS 0.4X2.5 VDE, 1205037.
Figure 49
Snapping the housing onto the DIN rail
Assembly
• If you use a DIN rail connector, then lay it into the DIN
rail with the protruding connector side facing left.
• Place the device onto a grounded 35 mm DIN rail from
above so that the upper housing slot hooks onto the top
edge of the DIN rail.
• Press the device carefully at the top of the housing towards the mounting surface.
• Once the snap-on foot has audibly snapped onto the
DIN rail, check whether it is securely attached.

Removing the base latch
To do so, you must first remove the spring, e.g. with a
screwdriver.
Then pull off the base latch.
To enable faster PCB removal, the hole on the
left-side can alternatively be an indentation in the
edge of the PCB. It would then not be necessary
to remove the base latch before removal (see
“Maximum PCB dimensions in the lower housing
part” on page 9).

Taking out the PCB
On the bottom of the housing there are two openings at
the outermost ends. Release the catch mechanism
there using a screwdriver. Keep both catch mechanisms open.
To remove the PCB, you have to slightly bend the housing wall up while pulling the Lock and Release system
forward at the same time.
Pull the PCB out.
