PM8AO
The PM8AO 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.
The module may be used as either a slave or master on the
Modbus network.
When used with a PC or PLC the module will be configured as a
slave. When used with a PM8AI module in a point-to-point
configuration, the DIP switch 9 must be turned on to set the module
up as a master. In this mode the PM8AO module will automatically
read the information from the PM8AI module and write the input
status to the outputs.
When used as a slave module, the outputs are written to by
the Modbus master device such as a PC or PLC.
