MM8VO - ANALOG OUTPUTS

The MM8VO 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 MM8AI 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 MM8AO module will automatically read the information from the MM8AI 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.
