4-CH analog input module / RS485

Category: SKU: 5NIZ4AI

NI204AI 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
  • 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
  • Dimensions: 17,5 x 100 x 112 [mm]
