Cephos C-TQ4 Relay module

The C-TQ4 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 two obsolete relays are the Panasonic TQ4 relay.

The Cephos C-TQ4 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)
