Part number:Z-8AI
8 CH AI module / RS485 ModBUS RTU

The Z-8AI is used to interface analog inputs (Voltage or current, also with bipolar range) with Modbus system. The modules is able to supply all 8 current loops at the sameb 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.

  • Voltage or current inputs with programmable range: ± 2 Vdc, ± 10 Vdc e ± 20 mA at 16 bits resolution.
  • The module’s auxiliary power supply can be supplied to all 8 current loop at the same time.
  • The Modbus address and the Baud rate can be set through DIP-switches.
  • The total cycle time can be set for all channels at 480 ms or 960 ms.
  • Current input with internal shunt that can be selected through DIP-switches.
  • Current input impedance ~ 50 O.
  • 1500 V ? output isolation compared with other low voltage circuits.
  • Removable terminals with section of 2.5 mm .
  • RS485 serial communication with Modbus-Rtu protocol, maximum 64 nodes.
  • Connection distance up to 1200 m.
  • RS232 port with jack 3,5 mm frontal connector, with communication’s automatic switching.
  • The device parameters can be set via the configuration software.
