## Summary description

Bistable installation relay ORNO OR-PI-456/24UC operates on 24 VAC/DC control voltage and provides a switching capacity of 16 A. Designed for electrical installations, it maintains its contact state after control pulse removal, reducing power consumption. Suitable for lighting, motor control and building automation where stable latching switching is required.

## Long description

The ORNO OR-PI-456/24UC bistable installation relay is a compact switching device designed for use in electrical installations that require a latching contact. It operates from a 24 VAC or 24 VDC control supply and provides a switching capacity of up to 16 A, allowing it to control lighting circuits, small motors and other building automation loads while retaining its contact state after the control pulse has ended.
Advantages
This bistable relay reduces continuous power consumption by maintaining its output state without the need for a sustained control signal. Its dual compatibility with 24 VAC and 24 VDC control voltages increases installation flexibility. The relay’s 16 A switching rating supports a range of common installation loads, and its DIN-rail or panel-compatible form factor simplifies mounting in distribution boards and control cabinets.
Suitable for
Controlling lighting circuits where latched switching is required
Operating small motors and actuators in automation systems
Integration into building automation and smart home control panels
Power circuits that benefit from reduced control power consumption
Key specifications
Control voltage: 24 VAC / 24 VDC
Contact type: bistable (latching) relay
Switching capacity: 16 A
Intended application: electrical installations, lighting, motor control, building automation
Mounting: panel or DIN-rail compatible form factor for distribution boards and control cabinets
How to use
Install the relay in a suitable enclosure or on a DIN-rail according to local electrical codes. Connect the 24 VAC or 24 VDC control input to the designated control terminals and wire the load to the switching contacts rated for 16 A. A short control pulse toggles the relay to the opposite contact state and the relay remains in that state until another pulse is applied. Ensure wiring, fusing and load characteristics conform to the relay’s voltage and current ratings.
Usage recommendations
Use appropriately rated fuses or circuit breakers on the load side and observe the maximum 16 A switching capacity. For inductive loads such as motors, include suppression or inrush-current mitigation as required by the load specifications. Verify compatibility with the control voltage source (24 VAC or 24 VDC) and follow installation standards for safe operation.
