Relay base for miniature relays

The Enfain ECOR-1-BSC3/2X21 relay base accepts miniature power relays or miniature switch relays with one or two switching contacts. It provides a screw connection for secure wiring and includes a plug-in option for an input or interference suppression module. The unit mounts on NS 35/7.5 DIN rail.

Replaces worn or missing relay sockets

This base serves as a direct replacement for a damaged or absent socket in control panels using the same relay footprint and DIN rail standard. The upgrade is worthwhile when the existing base shows contact degradation or when adding interference suppression becomes necessary for signal integrity.

Check relay contact count and rail compatibility

Verify that the relay you intend to fit has one or two switching contacts and matches the miniature form factor. Confirm the panel uses NS 35/7.5 DIN rail for mounting. Ensure the screw terminal pitch suits your wire gauges before ordering.

Questions about this item

Does this relay base mount on a standard NS 35/7,5 DIN rail?

Yes, the ECOR-1-BSC3/2X21 is designed for installation on NS 35/7,5 DIN rails, snapping directly onto the 35 mm rail profile.

How do I connect wires to the screw terminals without causing a loose connection?

Strip each conductor to the recommended length, insert fully into the screw terminal, and tighten the screw firmly; the common mistake is leaving too much bare wire exposed or under-tightening the screw.

Can I add an input or interference suppression module later without rewiring the base?

Yes, the base includes a plug-in option for an input/interference suppression module that can be added or replaced without disturbing the screw-terminal wiring.
