This Finder bistable relay (MPN: 20.23.9.012.4000) is designed for professionals in electrical control systems who need a reliable switching component for 12V DC applications. Its key benefit is the bistable (latching) functionality, allowing it to maintain its state without continuous power, saving energy. A potential caveat is its specific 12V DC control voltage requirement. This relay offers 1 make and 1 break contact, a nominal switching current of 16A, and DIN rail mounting for easy integration into control panels.

A bistable relay, also known as a latching relay, is an electromechanical switch that maintains its last switched position even after the control power is removed. It requires a pulse of power to change state (ON or OFF).
This Finder relay operates with a control voltage of 12V DC. The acceptable range is between 10.8V and 13.2V DC.
It features one changeover (CO) contact, which provides one Normally Open (NO) contact and one Normally Closed (NC) contact.
The relay has a nominal switching current of 16A and specific ratings for different lamp types (e.g., 2000W incandescent, 1000VA fluorescent). Ensure your load does not exceed these specifications.
It is designed for easy mounting on a standard 35mm DIN rail and occupies one module unit width.
No, as a bistable relay, it only consumes power momentarily when its state is being changed. It does not require continuous power to maintain its ON or OFF state, making it energy efficient.
Yes, this relay includes a manual actuator that allows you to switch the contacts directly without energizing the coil.
Verify the coil voltage is within the 10.8 - 13.2V DC range. Ensure correct polarity if applicable. Check wiring connections to the coil terminals (A1/A2). Ensure the manual actuator is not locked in a position that prevents switching.
Check the load connected to the contacts does not exceed the maximum switching current (16A nominal, 12A at cos phi=0.6) or voltage ratings. Ensure the relay is properly latched. Verify wiring to the contact terminals (e.g., 1, 2, 3).
Confirm the relay is a bistable type and intended for latching operation. Ensure the control signal is correctly applied and removed, and that the relay has successfully switched to its new state before de-energizing the coil.
Ensure the connected load does not exceed the relay's maximum switching capacity. Verify the ambient temperature is within operating limits. Check for loose connections which can cause resistance and heat.
