*1 Only Ethernet or expansion unit Modbus-RTU can be used.
*2 The analog output of the main unit is for the main unit only. The analog output of the sensor equipped with the sub unit requires an expansion unit (AO module).
The expansion unit (AO module) can also output analog signals from the sensor mounted on the main unit, allowing multi-core connections.
*3 When installing two or more sensors using subunits and using individual contact outputs, use an expansion unit (DO module).
In this case, the individual outputs for the sensor mounted on the main unit are output from the expansion unit (the main unit's contact are a collective output).
