ABB intermediate relays play an important role in connecting control systems with field devices, ensuring safe signal transmission and improving the overall performance of industrial electrical systems.

What Is an ABB Intermediate Relay and Why Is It Important?

An intermediate relay is an electrical switching component designed to control circuits by using a low-power control signal to operate a higher-power switching function.

In industrial automation applications, ABB intermediate relays are commonly used between PLC outputs and field devices. They provide electrical isolation, signal amplification, and additional switching contacts for complex control requirements.

Typical functions include:

• Electrical isolation between control and power circuits
• Signal conversion and amplification
• Expansion of PLC output contacts
• Protection of control system components
• Reliable switching of industrial loads

For automation engineers, intermediate relays are a critical part of maintaining stable communication between controllers and external equipment.
