Cephos C-NF4EB Relay module

The C-NF4EB relay module is manufactured by Cephos Electronic Circuits Ltd. in the UK - a relay module to replace a classic four pole changeover small signal Panasonic / Matsushita NF4EB relay that has not been manufactured for several years and is now obsolete and very difficult to source.

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)

The C-NF4EB relay module is fitted with a polarity selector switch for the on-board Axicom IM relays as the original relay was not polarised.

The IM relay is tested according CECC/IECQ and certified in accordance with IEC/EN 60950 and UL 60950

The Tyco / Axicom IM relay used is a fourth generation slim-line / low profile relay with bifurcated contacts
