Electromagnetic relay PK-4PR 12V 12V AC/DC contact: 2P I=2x8A 2R I=2x8A 1 module PK-4PR-12V

Electromagnetic relay – reliable circuit switching

The PK-4PR 12V electromagnetic relay is a component that will find application in both home and industrial installations. The device is designed for remote control of electrical circuits, allowing for safe and efficient switching of loads. The relay's design allows for mounting on a standard TH-35 rail, making it easy to integrate with existing systems.

Construction and application

The PK-4PR relay has two changeover contacts (NO/NC) and two normally open contacts (NC), providing great flexibility in circuit configuration. The coil supply voltage is 12V AC/DC, making it compatible with a wide range of power sources. The relay is particularly useful in applications requiring galvanic isolation between the control circuit and the load circuit. This provides additional safety and protects against interference.

The rated current of the contacts is 8A, allowing control of various receivers, such as lighting, heaters or small motors. It is important to remember the characteristics of the load – with inductive or capacitive loads (e.g. motors, switch-mode power supplies), a potential reduction in contact durability should be taken into account due to inrush currents during switching.

Key features and benefits

• Universal supply voltage: Possibility of powering with both direct (DC) and alternating (AC) 12V voltage.
• Contact configuration: Two changeover contacts and two normally open contacts provide flexibility in selecting the connection diagram.
• Mounting on TH-35 rail: Quick and easy mounting in standard electrical panels.
• Durability: Relay designed for long-term operation in various environmental conditions (operating temperature: -25 ÷ 50 °C).
• Safety: Galvanic isolation between the control circuit and the load circuit increases safety.
• Compact dimensions: Single-module housing (90 mm x 65 mm) allows for saving space in the switchboard.
• Screw connections: Ensure a secure and durable connection of wires with a cross-section of up to 2.5 mm².
• Protection class IP20: Protection against finger contact and against the ingress of solid objects larger than 12.5 mm.

The PK-4PR relay is a solid and reliable solution for every installer and user looking for an effective way to remotely control electrical circuits. Its versatility and ease of installation make it an ideal choice for a wide range of applications.
