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.
