Reed Relay Modules

A reed relay module contains multiple switching relays in a single device. Standex Electronics’ relay modules offer many package styles which include 8-channel and 4-channel relay versions. Our RM05-8A-SP series is an 8-pole (2C Matrix) configuration housed in a compact dual-in-line through-hole package. Furthermore the RM05-8A-SP comes equipped with the latest integrated drivers MAX4823 with kickback protection. Eliminating the need for external activation electronics. Finally there’s the 4-pole RM05-4A series low-profile surface mount design with ball-grid array. Also available in a plug-in version. Most notably the 4-pole series is a high frequency relay module capable of switching beyond 5.5 GHz. While boasting <40 ps rise times for switching fast pulses.
