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

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

Industrial remote controls are wireless input devices that are used to control machines and equipment to which they are not directly linked. They use radio frequency (RF) signals, digital pulses, or infrared light to send signals from transmitters to receivers

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

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

Data acquisition is the digitizing and processing of multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes. Signal conditioning includes the amplification, filtering, converting, and other processes required to make sensor output suitable for rereading by computer boards.

Electronic counters and electronic timers are completely electronic units for performing a variety of counter or timer functions.

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.

Telemetry receivers and telemetry transmitters are data acquisition components used to gather information from remote locations via wireless communication

Transfer switches transfer electrical power back and forth between two power systems or buses such as a utility power line and a backup motor-generator power supply.

Data acquisition systems and instruments collect, digitize and process multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes.

Thermocouple temperature transmitters convert the small millivolt output of a thermocouple to a current signal (typically 4-20 mADC) that is immune to noise and voltage drops over a long distance.

Video switchers control video display sequences for multiple camera systems.

Channel service units (CSU) and data service units (DSU) are digital interface devices that connect end user data communications equipment to digital access lines. They also provide framing of sub-64 kbps customer access channels onto higher rate data circuits.

Light curtain controllers send stop signals to machines that are guarded by light curtains, photoelectric transmitters that project an array of synchronized, parallel infrared light beams to a receiver.
