Intermediate Relay

Intermediate relay is an electromagnetic switch element widely used in automation control systems to isolate and amplify signals. It can convert one signal into multiple output signals to realize complex control logic. Intermediate relay plays a key role in the fields of power, automation control, instrumentation, etc. to ensure the stable operation of the system.

More Product Questions And Answers

What is an intermediate relay and what is it used for?

An intermediate relay, also known as an interposing relay, is used to interface between mismatched control signals and loads. It allows low-voltage logic outputs to drive higher-voltage contactors, or can act as a buffer to switch multiple loads from one signal. Intermediate relays provide isolation, signal conditioning and amplification between control and power circuits.

  • Matching control I/O to load requirements
  • Expanding the number of loads controlled by one output
  • Providing higher switching capacity than logic outputs
  • Isolating sensitive controls from electrical noise and surges
  • Simplifying troubleshooting and maintenance
  • Allowing control upgrades without power circuit changes
  • Input signal type (voltage, current) and range
  • Required coil voltage and power consumption
  • Output contact ratings and configuration (NO/NC/CO)
  • Expected electrical life (number of operations)
  • Operating speed and timing requirements
  • Mounting style (socket, rail/panel mount)
  • Environmental conditions (temperature, humidity, vibration)
