The inputs are isolated from the logic and share a common
The standard setting for the PM8AI/I module is 0 - 20mA
input current which represents an output value of 0 - 4095 (12
bits) in the corresponding Modbus register. To obtain an
output value of 0 to 4095 for an input signal of 4 to 20mA the
offset switch is switched on.
The same applies to the PM8AI/V module. An input voltage of
0 - 10Volts represents an output of 0 - 4095 and 2 volts would
give a reading of 819 ± 1LSB. To obtain an output value of 0
to 4095 for an input signal of 2 to 10V the offset switch is
switched on. An input range of 0(1) to 5Vdc is available by
removing the jumper link located on the analogue board
inside the enclosure.
