General Purpose Solid-State Relays

Available286 products

General purpose solid-state relays have no mechanical moving components and are unaffected by shock, vibration, or electronic noise. They have long service lives and are suitable for applications that must turn on and off quickly.

Surface-Mounted Relays

Surface-Mounted Relays

These relays have mounting features that secure with screws on surfaces like walls, control panels, and enclosures. They help protect relays from moving due to vibrations and impacts, making them ideal for applications around running motors.

MOSFET Switch Component Type

MOSFET (metal-oxide-semiconductor field-effect transistors) have an electrically-insulated gate between their source and drain terminals that controls the amount of electricity that can flow between them. They use electric fields to switch DC currents. They can switch at higher frequencies than a triac, but are not suitable for high-current switching.

Photocoupler Switch Component Type

Photocoupler uses light-emitting diodes (LED) and photodetectors to transfer signals and communicate feedback between isolated circuits quickly. They're suitable for high-voltage AC or DC signals and respond well to lower frequencies. They have long service lives and produce little electrical noise.

Phototriac Switch Component Type

Phototriac uses light-emitting diodes (LED) and photodetectors to isolate input and output circuits to protect low-voltage devices from high-voltages. They eliminate electrical chatter and deliver reliable results. Available in zero crossing and non-zero crossing.

SCR Switch Component Type

SCR (silicon controlled rectifier) is a solid-state unidirectional switch that only allows current to flow in one direction. They are used in high current and voltage applications to control AC circuits that change polarity.

Triac Switch Component Type

Triac (triode for alternating current) allow current to flow in both directions and can switch AC or DC current. Once they begin to conduct, they will continue to do so until the current reverses or reduces below the holding current threshold. They can switch much higher currents than a MOSFET but are generally limited to 50A or less.

DIN-Rail Mounted Relays

DIN-Rail Mounted Relays

These relays secure onto DIN-rails. They help save space and keep wires tidy in electrical enclosures, load centers, and equipment cabinet racks.

Combination DIN-Rail & Surface-Mounted Relays

Combination DIN-Rail & Surface-Mounted Relays

These combination relays snap onto DIN-rails and have mounting features that secure with screws onto flat surfaces like walls, control panels, and enclosures. They help protect relays from moving due to vibrations and impacts, making them ideal for applications around running motors.
