PM8VO - 8 Voltage Output Module

The PM8VO is a 8 channel voltage output module. Each channel can be set to output a voltage in the range 0 – 10V. 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 – 10V. A value of 819 ± 1LSB will give a current output of 2V.

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 PM8VO module will automatically read the information from the PM8AI module and write the input status to the outputs.
