Application: A Concord Series 8000 Pro Lift residential elevator, installed 2000. There are 15 G5LE-14 24VDC relays in the control panel. Architecture is analog. Each relay coil is energized when the elevator is idle (not in use). This strategy allows passive failover system-wide, but the relays eventually wear out. 25 years of this is probably pretty good. I have replaced 2, with plain-jane relays, no suffix codes. See the image.
Should I buy the CH suffix, for heat resistance? Should I look at something else?
