Provide a switch/circuit breaker close to the device,
which is labeled as the disconnecting device for this device.
Provide overcurrent protection (I ≤ 16 A) within the installation.
To protect the device against mechanical or electrical
damage, install it in a suitable housing with appropriate
degree of protection as per IEC 60529.
During installation, servicing, and maintenance work,
disconnect the device from all effective power sources,
provided you are not dealing with SELV or PELV circuits.
If the device is not used as described in the documentation, the intended protection can be negatively affected.
Thanks to its housing, the device has basic insulation to
the neighboring devices, for 300 Veff. If several devices
are installed next to each other, this has to be taken into
account, and additional insulation has to be installed if
necessary! If the neighboring device is equipped with
basic insulation, no additional insulation is necessary.
The voltages present at the input and output are extralow voltages (ELV). Depending on the application, dangerous voltage (> 30 V) to ground could occur at the input and output. The supply voltage could be a
dangerous voltage, depending on the application. All
connections are safely electrically isolated from each
other.

Method of operation

The passive isolator draws the power required for isolation
from the input signal.
When using passive isolators, make sure that the current
sourcing voltage of the measuring transducer UB is sufficient
to drive the maximum current of 20 mA via the passive isolator with a voltage drop UV = 2.9 V and load RB.
This means:
UB ≥ UE = 2.9 V + 20 mA x RB
UV = 2.9 V

Safety function
The defined safety function for the devices applies for the
input signal range of 4 ... 20 mA.
The device transfers a measuring signal of 4 ... 20 mA –
electrically isolated – into an output signal of 4 ... 20 mA with
a tolerance of 2%. The input signals are transferred in a linear 1:1 ratio.
The fault signal is defined for the ranges between 21 mA.
The analog output signal has to be evaluated using a downstream logic unit.
In the case of a two-channel, redundant application (1oo2),
you must compare the values and establish a safe state
when exceeding a certain tolerance.
8.2
Operating mode
Operating mode in accordance with EN 61508: "low requirement rate" or "high requirement rate" (six requirements per

8.3
Relevant standards
The device can be used in safety-related applications up to
SIL 3 (systematic suitability SC3). The standards which are
relevant to the intended purpose, such as EN 61508 and
EN 62061, must be applied.

Notes on operation
The output signal of the passive isolator in normal, uninterrupted mode is within the range of 3.6 ... 21 mA. If a fault or
error occurs during operation, the connected safety-related
controller establishes that a measured value is outside of
normal operation and initiates appropriate measures. As it
cannot be established whether the error was caused by the
passive isolator or by the devices connected upstream of
the passive isolator, you must check the entire safety loop
from the sensor to the output of the passive isolator.
After being switched off and on again, the required voltages
are established in the device. Signal transmission is then
performed without further action.

Recurring checks
8.9
Repair
The devices have a long service life, are protected against
malfunctions, and are maintenance-free.
However, if a device should fail, send it back to Phoenix
Contact immediately. The type of malfunction and possible
cause must also be stated.
Please use the original packaging or other suitable safe
packaging when sending devices back for repairs or recalibration.

The function of the entire safety loop must be checked regularly according to IEC/EN 61508 and IEC/EN 61511.
The intervals for checking are specified by the intervals of
each individual device within the safety loop.
It is the operator's responsibility to select the type of checks
and the checking intervals in the specified time period.
Checking must be carried out in such a way that the correct
function of the safety equipment in conjunction with all components can be verified.
Possible procedure for recurring checks for discovering dangerous and undetected device failures
A calibrated simulator (0/4 ... 20 mA current) or a sensor
simulator and one or ideally two calibrated digital multimeters are required in order to check the devices.
1. Take appropriate steps to prevent incorrect use.
2. Disconnect the safety circuit from further processing.
3. Connect the current simulator to the input of the repeater power supply/signal conditioner, or the sensor simulator to the input of the measuring transducer.
4. Connect the digital multimeters to the input and output
of the repeater power supply/signal conditioner.
5. At the input of the device, set a signal in the range from
4 ... 20 mA or at the input of the connected measuring
transducer, set a suitable signal with the sensor simulator.
6. Measure the current in the repeater power supply/signal
conditioner. The output must be set to the same value.
7. Setting ≤ 3.6 mA or > 21 mA verifies that the subsequent processing can detect signals that are out of
range and evaluate them accordingly. If the output value
deviates from the input value by more than 3 times the
specified class accuracy rating, the device should be
checked. In the event of an error, the device should be
replaced with an equivalent device.
8. Restore the safety circuit to full functionality.
9. Resume normal operation.

Meaning
Diagnostic coverage of dangerous failures:
DCD = DD/(DU + DD)
Diagnostic coverage of safe failures:
DCS = SD/(SU + SD)
1 FIT = 1 failure/109 h
Hardware fault tolerance: ability of a function unit to continue with
the execution of a demanded function despite existing faults or
deviations
Proportion of dangerous failures per hour
Proportion of detected dangerous failures per hour
Proportion of undetected dangerous failures per hour
Proportion of safe failures per hour
Proportion of detectable safe failures per hour
Proportion of undetectable safe failures per hour
Mean time between consecutive failures
Average probability of dangerous failure on demand of a safety
function
Probability of failure per hour for the safety function
The performance level indicates the capability of safety-related
parts of a control system to carry out a safety function in foreseeable conditions (PL: a, b, c, d, e)
Proportion of safe failures: proportion of failures without the potential to set the safety-related system to a dangerous or impermissible function state
International standard IEC 61508 defines four discrete safety integrity levels (SIL 1 to 4). Each level corresponds to a probability
range for the failure of a safety function. The higher the safety integrity level of safety-related systems, the lower the probability
that the demanded safety functions will not be performed.
