## Long description

ORNO OR-PI-457/1/UNI is a DIN-rail mounting installation relay with a single pole (1P) contact and a rated switching current of 16 A. The device features a universal control input that accepts 12–230 V AC or DC, allowing it to be driven from a wide range of control sources. Designed for electrical distribution boards in residential and commercial environments, this relay is intended for switching lighting circuits, small motors and resistive loads, and for use in basic automation applications.
Advantages
The relay’s universal control voltage simplifies inventory and installation by supporting both low-voltage and mains-level control signals without additional converters. Its DIN-rail form factor ensures straightforward mounting and integration into standard distribution enclosures. With a 16 A contact rating and a single-pole configuration, the unit provides reliable switching for common lighting and small-load circuits while maintaining compact dimensions for space-efficient panel layouts.
Suitable for
Switching lighting circuits in residential and commercial panels
Controlling small resistive loads and compact motors
Basic automation tasks and control logic in distribution boards
Retrofitting and replacement in DIN-rail installations
Key specifications
Contact arrangement: single pole (1P)
Rated switching current: 16 A
Control voltage range: 12–230 V AC/DC (universal input)
Mounting: DIN-rail
Intended application: electrical installations, lighting and small-load switching
How to use
Mount the relay on a standard DIN-rail inside the distribution enclosure and make the supply and load connections according to the installation diagrams provided by ORNO. Apply the control voltage within the 12–230 V AC/DC range to the control terminals to actuate the contact. Ensure that the switched load does not exceed the 16 A rating and that wiring and protective devices are selected in accordance with applicable electrical standards. Verify correct operation after installation by operating the control input and confirming contact switching under expected load conditions.
Usage recommendations
For reliable long-term operation, ensure the relay is used within its rated current and voltage limits, install appropriate overcurrent protection upstream, and avoid frequent switching of inductive loads without suitable suppression or protective components.
