Four pole telecom / signal relay, polarity selectable, 4 pole changeover / 4 Form C / 4PDT
The C-NF4EB relay module is manufactured by Cephos Relays 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.
These obsolete four pole relays are
Panasonic NF4EB
Omron LZN4
Zettler AZ7- 4C
The C-NF4EB relay module is a drop-in replacement for all 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)
