Low Signal Relay G5A 113
■ Approvals
UL (File No. E41515)/CSA (File No. LR24825)
Note: 1. The rated values approved by each of the safety standards (e.g., UL and CSA) may be different from the performance characteristics
individually defined in this catalog.
2. In the interest of product improvement, specifications are subject to change.
Hints on Correct Use
Single-winding type (G5AU)
Example of low-power drive circuit
1. The figure below shows a drive circuit (JAPAN PAT. NO. 1239293)
in which the latching relay can function like a general-purpose
relay from a normal input pulse for switching.
2. Use a charging current of capacitor C to operate the latching
relay, which flows suddenly through diode D1, capacitor C, latch-
ing relay, and diode D2, and the relay contacts will be put in the
locked state.
3. Use a discharging current of capacitor C to release the latching
relay, which flows through transistor TR, capacitor C, and the
latching relay.
Note: 1. When applying the relay for practical use, make sure of the
set or reset state of the relay; then determine the circuit con-
straints.
2. Because OMRON possesses the patent of this drive circuit,
contact OMRON when adopting it.
