Technical Specifications

B. Working Principle

The Omron P2RF-08-PU works as an intermediate mounting and wiring interface between a plug-in relay and an electrical control system.

Working Process:

1. The Omron G2R-2-S relay is inserted into the P2RF-08-PU socket.
2. Control signals are connected through the Push-In Plus terminals.
3. The socket transfers coil power to energize the relay.
4. When the relay coil activates, the relay contacts switch the connected load circuit.
5. The socket provides a stable mechanical and electrical connection between the relay and field wiring.

The Push-In Plus terminal system uses spring clamp technology. Wires or ferrules can be inserted directly into the terminal without tightening screws, providing secure contact with reduced installation time.

For stranded wires, a flat blade screwdriver can be inserted into the release hole while inserting the wire into the terminal. After removing the screwdriver, the spring mechanism securely holds the conductor.

C. Why It Is Used

The Omron P2RF-08-PU relay socket is used in industrial automation systems where reliable relay installation and efficient panel wiring are required.

Main Benefits:

1. Faster Panel Wiring

Push-In Plus technology reduces wiring time compared to traditional screw terminals. Omron testing indicates wiring time reduction of up to 60% compared with screw terminal methods.

2. Reduced Maintenance

Since there are no terminal screws that can loosen over time, the socket provides improved long-term reliability and reduces maintenance requirements.

3. Reliable Electrical Connection

The socket provides strong pull-out strength while maintaining low insertion force, ensuring secure connections in industrial environments.

4. Easy Relay Replacement

The integrated release lever allows technicians to quickly remove and replace relays during servicing.

5. Flexible Installation

The socket can be installed on DIN rails or mounted using screws, making it suitable for different control panel designs.
