Analog input module Z-4AI

Modbus RTURS-4854-channel

Z-4AI is used to interface analog inputs (Voltage or current, also with bipolar range) with Modbus system. The modules is able to supply all 4 current loops at the same time, this is very useful for 2-wire sensors because the wiring does not need an external power supply. It’s a ModBUS Slave and can be coupled with any ModBUS Master device. A 3-way galvanic isolation among Power supply // input // RS485 circuits assures the integrity of your datas. Power supply: - 10..40 Vdc; 19..28 Vac (50-60 Hz) Transducers supply: - 13 Vdc, 90 mA Dimensions: - 17,5 x 100 x 112 [mm] Mounting: - DIN 46277, 25 mm symmetrical rail Input: - CH-4 voltage (up to a ±10 Vdc) or current range (up to ±20 mA) Resolution: - 15 bit + sign Communication: - RS485 2 wire, ModBUS RTU slave protocol
