About us
General
The TBX DES 16S04 is a modular base unit comprising 16 120 V AC inputs, compatible with 2 wire CENELEC proximity sensors. The module is equipped with a terminal block for direct wiring of the sensors, 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.
