Output Relay Contact
If E3JM/E3JK is connected to a load with contacts that spark when the load is turned OFF (e.g., a contactor or valve), the normally-closed side
may be turned ON before the normally-open side is turned OFF or vice-versa. If both normally-open output and normally-closed output are used
simultaneously, apply an surge suppressor to the load.
Refer to OMRON’s PCB Relays Catalog (X33) for typical examples of surge suppressors.
