Introduction to the TBX ESP 1622 Module
(Original Document)
About us
General
The TBX ESP 1622 sealed (IP65) remote output module is a monobloc module comprising 16 24 VDC 0.5 A transistor outputs.
It is equipped with M12-type connectors for direct wiring of the pre‐actuators.
The outputs are protected against overloads and short-circuits.
When there is a fault at an output, the I/O indicator lamp lights and the output is set to state 0. To reactivate it, this output must be reset once the fault has been rectified.
The preactuator voltage is monitored to ensure consistent processing of the outputs during variations in the power supply.
