Z-4DI-2AI-2DO is a I/O module with 4 digital inputs, 2 analog inputs, 2 relay outputs, slave for Modbus RTU, on two RS485 serial ports. The module allows the possibility to set the parameters via USB (Easy setup software) an registers repetition on Modbus RTU protocol (NR.2 independent RS485 slave ports). Baud rate for ModbusRTU is from 1.200 up to 115.200 bps. Signal configuration include 2 analog inputs (voltage or current), 4 digital inputs (NPN or PNP), 3 relay outputs, 4 counters and 4 totalizers @ 32 bits, max 7 kHz. Z-4DI-2AI-2DO has 1.500 Vac galvanic isolation between power supply and communication.
