ZC-24DI is used to interface N.24 digital signals (PUSH BUTTON, LIMIT SWITCH, REMOTE, CONTROL SWITCH, RELAIS etc.) with all of control systems which are able to communicate by the protocols CANopen or ModBUS RTU (protocol selectable through dip-switch). It disposes of 32 bit counters (N.8), maximum frequency input is 10 KHz. A 3-way galvanic isolation among Power supply // input // RS485 circuits assures the integrity of your datas.
