●
For internal supply, ONLY USE te24 V and NEVER USE termi‐
nal +10 V or +5 V!
●
For external supply, its reference ground MUST be connected to termi‐
nal COM!
Relay output terminals
When relay output terminals are connected with inductive loads (relays, con‐
tactors, solenoid valves, motors, etc.), following noise suppression circuits
need to be applied at the coils of the inductive loads, as close as possible to
the inductive loads, in order to reduce the electromagnetic interference gen‐
erated from inductive load action.
