Four pole telecom / signal relay, polarity selectable, 4 pole changeover / 4 Form C / 4PDT
This relay module is fitted with polarised signal relays, the polarity selector switch enables easy integration into any relay circuit that previously used the original obsolete non-polarised relays.
The CH-NF4EB 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 NF4EB, Omron LZN4 and Zettler AZ7-4C relays.
The C-DS4E relay module is a drop-in replacement for all of these relay types
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)
