Cephos C-DS4E Relay module

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

These obsolete relays are the Panasonic / Nais / Matsushita DS4E, the Omron G6A-434P and Fujitsu RA4 four pole changeover relays.

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)
