It is connected on 8 inputs of a IP20 module, and enables the following to be simulated:
-
either the presence of a sensor without leakage current (for example a dry contact or a 3-wire proximity sensor)
-
or the presence of a sensor with leakage current (for example a 2-wire proximity sensor).
The green LEDs indicate the state of the sensor:
The input simulator is fixed directly to the screw terminal of the TBX module (
terminals I0 to I7, I8 to I15 or I/O8 to I/O15). The common wire (white) must be connected to a +Cs, +Csm,n+1 or +C (24 V DC)
terminal.
To simulate all the TBX module inputs (I0 to I15), two input simulators are required:
NOTE: For TBX mixed modules, the input simulator is used with an output simulator.
The following diagram shows the switches that can be used with input simulators.
Description: SW2 in upper position
SW2 in upper position: simulates a sensor without leakage current.
Description: SW2 in lower position
SW2 in lower position: simulates a sensor with leakage current (2-wire proximity sensor).
