OVL1 24VAC/DC

The OVL1 24VAC/DC is a Coupling Relay with automatic (AUTO), permanently OFF (0) and permanently ON (HAND) functions. Automatic (AUTO) - the contact of check back B1-B2 is closed. The output relay R switches into ON-position (yellow LED illuminated) when the signal voltage applied at the terminals YR-A2 exceeds the value adjusted at the regulator. The output relay switches into OFF-position (yellow LED not illuminated) when the signal voltage falls below the set value by more than the fixed hysteresis. Permanently OFF (0) - the contact of check back B1-B2 is opened. The output relay R remains in OFF-position (yellow LED not illuminated) independent from the connected signal voltage. Permanently ON (HAND) - the contact of check back B1-B2 is opened. When the supply voltage U is applied at terminal A1 the output relay R switches into ON-position (yellow LED illuminated). Changes of the signal voltage do not influence the state of the output relay.
