6.5.5.5 4-channel analog output terminal 0 mA to 20 mA
The 4-channel analog output terminal 0 mA to 20 mA has four output channels and generates signals that must be
strictly restricted to 4 mA to 20 mA by an internal scaling installed in Data Manager M. This allows for direct wiring of
four 2-conductor actuators on the bus terminal. The actuators are connected to the CAGE CLAMP® connections AO 1
and ground or AO 2, AO 3, AO 4 and ground. The channels have one shared ground potential.
A green LED indicates the operating state and error-free terminal bus communication. A red error LED indicates a short
circuit or an overload.
