Continuation “External Encoder Supply”

Example of an external encoder supply (2 encoders are switched via 1 relay)



An external encoder supply must be done in each case via a relay which is triggered by
the auxiliary voltage of the unit.



The operator must ensure that the plant cannot reach a safety-critical state, in case of a
failure of the relay or a failure of the external encoder voltage (switched by the relay).
