CH-DS4E Relay Module

Description

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

Product details

The CH-DS4E relay module is manufactured by Cephos Electronic Circuits 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 the Panasonic DS4E, Omron G6A-434, Fujitsu RA4 and 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)
