Digital I/O Module Engineering Information
I/O MODULES
Our line of pluggable input and output modules
provide a low cost, versatile method for
interconnecting real world analog and digital
signals to data acquisition, monitoring, or control
systems. All modules provide an optically
isolated barrier between sensitive
microprocessor or digital logic circuits and
field power devices.
In the G5 and OpenLine® packages, analog
and digital I/O modules are available with the
same pin-out. This gives the flexibility of mixing
and matching module types on the same
mounting rack or base; making them perfect
in applications which require interface to a
variety of different sensors and loads.
The case color of the single point modules
identify their function. The industry standard
for single point I/O module case colors is:
Digital AC Output Module = Black Case
Digital DC Output Module = Red Case
Digital AC Input Module = Yellow Case
Digital DC Input Module = White Case
DIGITAL OUTPUT MODULES
Digital output modules are used to switch AC
and DC loads such as solenoids, motors, or
lamps from logic signal levels. Their inputs are
directly compatible with TTL or CMOS interface
circuitry.
AC output modules have zero voltage turn-on
of the load to greatly reduce generated EMI
and RFI. They are highly immune to electrical
transients, and have built-in RC snubber
networks for increased capability with inductive
loads.
DC output modules can operate DC loads over
a wide voltage range and have built-in voltage
spike protection.
DIGITAL INPUT MODULES
Digital input modules are used to monitor the
status of a load or a sensor (such as a limit
switch, pressure switch, or temperature
switch). The output of these modules is a logic
level signal which corresponds to the status of
the device being monitored. A high level output
signal indicates the load is off (the switch is
open). A low level output signal indicates the
load is on (the switch is closed). Input modules
are designed to give fast, clean switching by
providing filtering and hysteresis.
Input and output modules are compatible in
that the output of one can drive the input of the
other.
UL, CSA AND CE APPROVALS
As one of the world's leading manufacturers of
I/O modules, we strive to assure that our
products comply with all of the applicable
international standards. In doing so, we believe
your products will also be readily accepted and
easily certified. All modules shown in this
section have been tested to UL Standard 508
and are documented in UL file number E58632.
Similarly, they have been tested to CSA
Standard 22.2 No. 14-95M and are documented
in CSA file LR38763. Additionally, OpenLine®
modules were tested and passed CSA 22.2
No. 213-M1987 Class I, Div. 2 Groups A, B, C
and D. Parts bearing the CE logo indicate
conformance with EN50082-2 and EN50081-2
(89/336/EEC EMC directive) as well as EN60950
(61010-1) for the low voltage directive. Contact
Grayhill for copies of our Declaration of
Conformity or visit out website. Parts bearing
the TÜV logo indicate that they were the agency
which performed the EN60950 evaluation.
CONSTRUCTION AND LIFETIME
WARRANTY
All of our I/O modules are hard potted with
thermally conductive epoxy to withstand harsh
industrial environments. The modules provide
optical isolation, immunity to mechanical shock
and vibration, and operate over a wide
temperature range. The module cases are a
solvent resistant thermoplastic which meets
UL94-V-0 rating. The terminal pins are a tinplated copper wire. Component selection and
surface mount construction allow low operating
junction temperatures for long life. Superior
design, rigorous testing, and field data give us
the confidence to back our I/O modules with
the industry's first lifetime warranty.
I/O MODULE WIRING
Analog and digital modules can be placed at
any I/O location, however, to minimize the
possibility of crosstalk and noise pickup it is a
good practice to group similar module types
together. 14 or 16 gauge wire is typically used
to wire the field devices to the I/O rack terminal
block.
