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 CH-MT4 relay module is manufactured by Cephos Electronic Circuits 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 the Tyco / Axicom MT4 and the Siemens V23104 relays.
The CH-MT4 relay module is a drop-in replacement for all versions of these relay types
The Cephos CH-MT4 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)
