What is a general purpose relay and what is it used for?

A general purpose relay is a versatile electromagnetic relay designed for a broad range of switching and control applications. They are used to control motors, lights, solenoids and other electrical loads in response to signals from sensors, switches, control modules and logic devices.

What are the typical specifications of a general purpose relay?

Coil voltage rating (AC or DC) and resistance/power consumption
Contact type (normally open, normally closed, changeover)
Contact material (silver, gold, etc.) and ratings for voltage, current and power
Operate and release times
Mechanical endurance (number of operations)
Mounting type (plug-in, PCB, panel/surface mount)

How do you select the right general purpose relay for an application?

Coil voltage – should match the available control signal voltage
Contact ratings – must exceed load requirements with a safety margin
Number and type of contacts – determined by switching configuration
Expected mechanical and electrical life based on frequency of operation
Operating environment – consider temperature, humidity, vibration etc.
Physical size and terminal layout to fit available space
