Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications

Specialty relays and accessories are specialty or proprietary products and accessories related to relays

Scales and balances are used to measure static or dynamic loads for a wide range of industrial applications.

High voltage relays are used to transfer power for high voltage and high frequency applications. They are heavily insulated and consist of strong materials to increase contact life

Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other

Protective relays and monitoring relays detect or monitor for abnormal power system conditions

Time delay relays and solid state timers use solid state electronic devices to provide a time delay

Fire alarm control panels (FACP) are systems which receive information from input devices (smoke detectors, heat detectors, etc.), process the information, and trigger an output device such as an audio or visual alarm

Reed relays are electrically-operated switching devices that consist of two thin, magnetic strips (reeds) encapsulated in a glass envelope. They are used to switch industrial components such as solenoids, contactors and starter motors

Relay sockets are devices that accept relays, electromechanical switches in which the variation of current in one electric circuit controls the flow of electricity in another circuit

Pneumatic relays and volume boosters control output air flow and pressure in response to a pneumatic input signal. They can perform simple functions such as boosting or scaling the output, or use complex reversal, biasing, and math function operators

Safety relays and control modules differ from conventional relays in that they have force-guided or positive-driven contacts

Relay boards (multiple relay modules) are computer boards with an array of relays and switches. They have input and output terminals and are designed to control the voltage supply

Audible alarms provide an audible indication of a hazardous situation

Overload relays prevent an electric motor from drawing too much current and overheating; includes thermal and solid state overload types
