What is a General Purpose Relay?
General Purpose Relay Definition
General Purpose relays are the origin of the Omron relays, and they meet various needs with a wide variety.
They also are used in a variety of control components at production sites where high reliability is required and in control systems such as electricity, water, and gas.
General Purpose Relay Types
|For control panels||Relays with 1 to 4 poles are mainly used for relay sequences or I/O applications||MM(K), MK(S), MY, LY, G2R, G2RV, G7T, etc.|
|Built-in||Built-in relays enable using a carry current of up to 40 A and are used for building into devices, e.g., to turn ON load power supplies.||G7Z, G7J, G7X, etc.|
|For work saving||Work-saving relays are available in relay units and are used mainly for I/O applications for programmable controllers when downsizing and saving work are required.||G6D-F4B, G6B-4BND, etc.|
|For special operations||Relays for special operations are available as relays or relay units that are specified for a specific applications, such as alternative operation and stepping operation of pumps.||G4Q, G9B, MYA, etc.|

Transparent cases are used for most of these relays so that users can see inside of the relays.
In addition, indicators and mechanical latching levers contribute to a reduction of man-hours for checking operation and inspections.

General Purpose Relay Features
General Purpose Relay Application Examples
General purpose relays are mainly used as a control circuit (relay sequence) for control circuits of automated machines used at various production sites, and for various control systems such as lighting, air conditioning, and water treatment of buildings.
Omron has a wide variety of relays in accordance with the use environment and the purpose. (Mini-power relays, latching relays, etc.)
Construct control circuit by combining basic four circuits (NOT circuit/AND circuit)/OR circuit/X-OR circuit) with relays.
Used as a relay for relaying a load of a controller such as a PLC etc. and of a solenoid valve etc.
Application Lighting, air-conditioning control, etc.
Control to support the infrastructure
Application Traffic (not associated with running and stopping control), water supply, information, etc.
Digital switching system
Application Electricity, Steel, Shell Gas, etc.
Application Machine for manufacturing automobiles, Semiconductors, Chemicals etc.
