It integrates an LED indicator, a suppression diode, and a test button directly into the relay housing, which simplifies panel wiring and troubleshooting by eliminating separate socket-mounted components.
Contact material and switching capability
The contacts use silver cadmium oxide with a gold-plated overlay. The gold plating ensures reliable switching at low signal levels (dry circuits) where standard silver contacts may oxidize and fail to conduct. For audit purposes, this material selection is documented on the Omron datasheet and supports applications from millivolt-level logic signals up to the relay's rated load.
