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

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

Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They include a power supply, amplifier, user interface, and position control circuitry

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

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

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

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

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

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

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

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

Lighting controls include monitors, communication systems, and other devices for controlling facility lighting systems

Control panels are used to receive inputs, trigger outputs, and monitor systems and instrumentation. They are used in a variety of industrial, manufacturing and process control applications

Programmable automation controller (PAC) systems consist of PAC modules, each of which performs a specific function. PAC systems are used in motion control, machine control, machine vision, and other industrial control applications
