The JZ744 JZ762 interposing relay provides reliable electrical isolation and control signal transfer between lowvoltage control circuits and higherpower loads. Designed as an intermediate relay, it enables a small control current to safely switch larger currents in a separate circuit, protecting controllers and simplifying wiring in automation panels. This listing highlights the JZ744 220V coil version, with coil options available across the JZ7 family (including 220V, 110V, 36V, 24V, and 380V). Key benefits Electrical isolation between control and power circuits for safer operation and easier fault tracing. Lets lowvoltage control signals drive higherpower devices without loading the control circuit. Compact, panelfriendly size suitable for spaceconstrained installations. Flexible coil options across the JZ7 family, including 220V, 110V, 36V, 24V, and 380V variants. Simple integration into existing JZ744 or JZ762 based control schemes, aiding modularity and maintenance. Reliable switching performance to support automation tasks in industrial environments. Key attributes Functionality: interposing (intermediate) relay to bridge control circuits and current loads. Compatibility: designed to work within the JZ744 and JZ762 family of relays; available in multiple coil voltages including 220V (this listing is the JZ744 220V size variant). Size: JZ744 220V version for compact panel installations. Voltage options: coil voltages include 220V, 110V, 36V, 24V, and 380V, enabling selection to match control circuitry. Construction: robust interposing relay suitable for integration into standard control panels and machine wiring. Performance orientation: designed to provide dependable signal transfer and load switching in automation contexts. Two to three use cases Case 1: PLCbased machinery control can energize a current motor starter via the JZ744 220V coil version, using the relay to isolate the PLC output from the motor circuit while safely transferring the control signal. Case 2: Panelready sequencing and interlock logic in automated lines. The interposing relay accepts a lowvoltage control signal and drives downstream relays or contactors that handle higherpower actuation, improving safety and reliability. Case 3: Control cabinet expansion where multiple control schemes require clear separation between control logic and power circuits. The JZ744 220V variant supports straightforward interchangeability with other JZ7 models, enabling scalable wiring and easier maintenance.
