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 C-NF4EB relay module is manufactured by Cephos Electronic Circuits Ltd. in the UK – a relay module to replace two classic telecomms. small signal relays that have not been manufactured for several years and are now obsolete and very difficult to source.
The C-NF4EB relay module is a drop-in replacement for both of these relay types.
The Cephos C-NF4EB – 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)
