Input simulators for discrete TBX (IP20) modules
(Original Document)
General
It is connected on 8 inputs of a discrete TBX IP20 module, and enables the following to be simulated:
The green LEDs indicate the state of the sensor:
Connection
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.
Illustration
The following diagram shows the switches that can be used with input simulators.

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).
