Two pole telecom / signal relay, polarised, 2 pole changeover / 2 Form C / DPDT
The C-BT53 relay module is manufactured by Cephos Electronic Circuits Ltd. in the UK – a relay module to replace several classic telecomms. 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 C-BT53 relay module is a drop-in replacement for all of these relay types
The Cephos C-BT53 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)
Our suggested alternative is the
CH-BT53 relay module
which is IN STOCK
We are UK based and ship direct, worldwide.
