Z-D-IN is used to interface 5 digital signals (PUSH BUTTON, LIMIT SWITCH, REMOTE, CONTROL SWITCH, RELAYS, etc.) with all of control systems which are able to communicate by the protocol ModBUS RTU through the RS485 serial interface. A 16 bit counter is available on each input, the maximum frequency input is 100 Hz and it is possible to set one input as a fast counter with a maximum frequency of 10 kHz. The module is ModBUS Slave and can be coupled with any ModBUS Master device. A 3-way galvanic isolation among power supply, input, and RS485 circuits assures the integrity of your data.

Inputs: 5 Channel (Reed, Proximity, PNP, NPN, Contact) with common negative, self powered 24 VDC, isolated, protected from transient up to 600 W/ms
