Four pole telecom / signal relay, polarity selectable, 4 pole changeover / 4 Form C / 4PDT
The C-MT4 relay module is manufactured by Cephos Relays Ltd. to replace some 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
Tyco / Axicom MT4
Siemens V23104
The C-MT4 relay module is a drop-in replacement for all versions of these relay types
The Cephos C-MT4 5V, 12V and 24V coil voltage versions are normally ex-stock and available for immediate shipping, other coil voltages such as 48V are manufactured to order on a short lead time.
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.
5V and 12V versions are on a short lead time
