The PT8AOI is a 8 channel current output module. Each channel can be set to output a current in the range 0 – 20mA. The outputs are isolated from the logic and share a common negative terminal.
The resolution is 12 bits, so writing a value to the Modbus register for each output of 0 – 4095 would give an output current of 0 – 20mA. A value of 819 ± 1LSB will give a current output of 4mA.
