What Is the G5V-1? Signal Relay: Specs and Uses
The G5V-1 (Omron) is a low-power signal relay (SPDT). With its small size and low coil power it is used for signal/low-current (~1 A) routing (instruments, audio lines, battery-powered devices). Unlike power relays its current is low but its coil power is also low. Drive the coil with a transistor + add a flyback diode.
The G5V-1 (Omron) is a low-power signal relay (SPDT). With its small size and low coil power, it is used for signal/low-current routing rather than power switching. For the concept, see what is a relay.
What is the G5V-1 used for?
Test/measurement instruments, audio/signal line routing, low-current switching and battery-powered devices. Unlike power relays such as the SRD/JQC its current is low (~1 A), but its coil power is also low (battery-friendly).
Watch out
Still drive the coil with a transistor and add a flyback diode. Because the contact current is low, do not use it for high-current loads (use the SRD/JQC/SSR for those).
