Four pole telecom / signal relay, polarised, 4 pole changeover / 4 Form C / 4PDT
The CH-TQ4 relay module is manufactured by Cephos Electronic Circuits Ltd. in the UK – a relay module to replace a classic telecomms. small signal relay that has not been manufactured for several years and is now obsolete and very difficult to source.
This obsolete relay is the Panasonic TQ4 The CH-TQ4 relay module is a drop-in replacement for this relay
The Cephos CH-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)
