Power Supply Connections - Phoenix Contact PSR-TRISAFE-S Mode D'emploi

4. Installation
WARNING: Danger
Never carry out work when mains voltage is present
The PSR-TRISAFE-S configurable safety module is equipped with a TBUS
interface on its mounting side for standard extension modules.
Gateways for transmitting standard diagnostic values can be connected via the
TBUS DIN rail connector (INTERFACE system communication). The DIN rail
connector means there is no need for cross-wiring between the safety module
and the extension modules.
CAUTION:
• You must use the yellow PSR-TBUS (Order No. 2890425) for
connecting the PSR-TRISAFE-S safety module.
• Do not use a terminating connector.
• You must use the green TBUS (Order No. 2707437) for
connecting standard extension modules (e.g., PROFIBUS
gateways).
• Installing the devices on and removing them from the TBUS
is only permitted in a de-energized state.
• Standard extension modules must be installed on the
left-hand side of the safety module.
• When using DIN rail connectors, connect the required number of TBUS
connectors together and push them onto the DIN rail.
• When positioning the PSR-TRISAFE-S, please ensure that it is aligned
correctly with the TBUS on the DIN rail.
• When using the PSR-TRISAFE-S safety module, yellow and green TBUS
modules should be installed side by side.
• Place the yellow safety module on the yellow PSR-TBUS and the green
extension modules on the green TBUS.
5. Connection notes
WARNING: Danger
Never carry out work when mains voltage is present
Generally speaking, there are a large number of applications which use multiple sensors or controlling
devices. Depending on the size of the machine or system, a considerable amount of cabling may be
required to wire the sensors. Make sure that the specified cable lengths are not exceeded, so as to ensure
error-free operation of the safety circuit.
In order to comply with the UL, use copper cables that are designed for operating temperatures of 75°C.
To ensure the contacts are reliable and touch proof, strip the cable ends as shown below (Fig. 4).

In order to prevent interference, please always connect the two conductor ends at both
the inputs and the outputs.

5.1. Power supply connections

You must, without exception, connect both power supply connections to ensure that the
safety module functions correctly.
• Power supply connection for logic and monitoring outputs A1 and A2
The A1/A2 power supply connection is used to supply both the safety
module's logic and the monitoring outputs with power. Two-wire and
three-wire sensors and control devices can be supplied by the safety
controller directly (U
nom
Using three-wire sensors:
Please ensure the GND potential of the sensor/control device
matches the GND potential of the safety module.
• Power supply connection for 24 V/0 V outputs
The safety module's outputs and the clock and ground switching outputs
are supplied with power via the 24 V/0 V power supply connection.
5.2. Signal inputs I0 to I19
CAUTION: When connecting the signal cables of two-channel control devices and
sensors at controller inputs, please ensure that signal redundancy is present.
CAUTION: Prevent cross circuits and short circuits using a suitable cable installation.
The controller has 20 digital signal inputs (I0 to I19) for direct connection of safe control devices and/or
safety sensors for monitoring and evaluating processes.
Specification for inputs: 24 V/4 mA.
Using two-channel sensors/control devices:
In order to ensure signal redundancy, the prepared double signal must be used in each case for
the purpose of processing two-channel signals (two-wire sensors and control devices). For

example, in order to be able to monitor or evaluate the two signals of an emergency stop control
device redundantly and to performance level PLe as per ISO 13849-1 (formerly EN 954-1,
Category 4), these must be connected at two consecutive signal inputs (e.g., I0 and I1).
The safe inputs are linked to the safety logic in the connection editor of the SAFECONF configuration
software. For additional information, please refer to the user manual.
