C-DS4E Relay Module

Description

Four pole telecom / signal relay, polarised, 4 pole changeover / 4 Form C / 4PDT

Product Details

The C-DS4E relay module is manufactured by Cephos Relays Ltd. in the UK – a relay module to replace several classic telecomms. small signal relays that have not been manufactured for several years and are now obsolete and very difficult to source.

The more common of these obsolete relays are:
Panasonic DS4E,
Omron G6A-434
Fujitsu RA4
IMO-EN4-CW relays.

The C-DS4E relay module is a drop-in replacement for all of these relay types

Coil Voltages

The Cephos C-DS4E 5V, 12V and 24V coil voltage versions are normally ex-stock and available for immediate shipping, other coil voltages are manufactured to order on a short lead time (subject to component availability)

Current stock availability

5V and 12V on a short lead time

24V available from stock
