Some applications in mechanical engineering require the use of higher voltages, such as heating systems. Taking this into account, the new u-remote 4DI-2W-230V-AC module now also processes high AC voltages. And thanks to the galvanic isolation of each individual channel, up to four different voltages can be read in on one I/O module. It can be used for 110/230 V AC signals with 50/60 Hz and is compatible in accordance with EN 61131-2 type 3 (P-switching). Sensors such as encoders, switches and proximity sensors can be connected to each of the four digital inputs (2-wire connection).
