Introduction to the TBX DMS 1025 module
(Original Document)
About us
General
The TBX DMS 1025 is a modular base unit comprising 8  24 V DC inputs, compatible with 2 and 3 wire proximity sensors and 2 50 VA relay outputs. The module is equipped with a terminal block for direct wiring of the sensors and preactuators, which can be removed when it is switched off.
The sensor voltage is monitored to ensure that there is sufficient voltage for the inputs to operate correctly.
The inputs of this module have functions which, in certain cases, are common to a group of channels. Thus, it is possible to assign the 2 channel groups of the module to the various tasks in the application.
