About us
General
The TBX DMS 16S44 is a modular base unit comprising 8 120 V DC inputs, compatible with 2 wire CENELEC proximity sensors and 8 120 VA triac 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 and preactuator voltage are monitored to ensure that there is sufficient voltage for the inputs to operate correctly and for coherent processing of the outputs.
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.
