General Purpose Relays: An Overview
A general-purpose relay is an electrical switch activated by an electric current. These relays can operate with either AC or DC current and can be either normally open or normally closed. Their versatility makes them suitable for controlling various devices, including motors, lights, and fans.To get more news about General purpose relay, you can visit our official website.
Types of General Purpose Relays
Control Panel Relays: These relays typically have 1 to 4 poles and are used for relay sequences or I/O applications.
Built-in Relays: Designed for carrying currents up to 40 A, these relays are built into devices to turn ON load power supplies.
Work-Saving Relays: Used mainly for I/O applications in programmable controllers, these relays help downsize and save work.
Relays for Special Operations: These are specified for specific applications, such as alternative operation and stepping operation of pumps.
Applications
Relay Sequences: Construct control circuits by combining basic circuits (NOT, AND, OR, X-OR) with relays.
I/O Relays: Used to relay loads from controllers (e.g., PLCs) and solenoid valves.
Building Automation: Control lighting, air conditioning, and other building systems.
Infrastructure Support: Includes traffic control, water supply, and smart meter applications.
Plant Automation: Used in electricity, steel, gas, and other industrial plants.
Factory Automation: Found in manufacturing machines for automobiles, semiconductors, and chemicals.
Features
Transparent Cases: Most general-purpose relays have transparent cases, allowing users to see inside and check operation.
Indicators and Latching Levers: These features reduce man-hours needed for operation checks and inspections.
