Programmable logic controllers (PLCs) are the control hubs for a wide variety of automated systems and processes. They use a wide variety of inputs and outputs and provide network capability.

Logic gates are electronic circuits that combine digital signals according to boolean algebra

Programmable automation controllers (PAC) are compact industrial controllers used in applications such as data acquisition and control, machine vision control, and process control. PACs are functionally similar to programmable logic controllers (PLC), but provide the advanced software features of personal computers (PC

Web tension indicators measure and report tension parameters in web or other flat-sheet production processes. Some types of web tension indicators have control functionality as well.

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.

Programmable logic devices (PLD) are designed with configurable logic and flip-flops linked together with programmable interconnect. PLDs provide specific functions, including device-to-device interfacing, data communication, signal processing, data display, timing and control operations, and almost every other function a system must perform.

Industrial electronic repair services fix, repair, overhaul, refurbish, and warranty industrial electronic equipment such as power supplies, motor drives, controllers, meters, and oscilloscopes.

Universal process controllers constitute a broad area of control devices that may be employed in the monitoring and control of many different process variables, including temperature, pressure, flow and other values.

Calibration and repair services for vibration, acoustic, electrical / electronic test, environmental, dimensional, NDT, analytical, process and other specialty instruments, sensors and related equipment.

Fiber optic couplers are optical devices that connect three or more fiber ends, dividing one input between two or more outputs, or combining two or more inputs into one output.

ISDN testers verify the communication services provided by ISDN equipment.

Trackballs are computer pointers resembling an inverted mouse. The pointing ball is rotated with the thumb, fingers, or the palm of the hand.

Device programmers are used to program nonvolatile memory such as microcontrollers, erasable programmable read-only memory (EPROM), programmable logic devices (PLDs), programmable array logic (PAL), generic array logic (GAL) and other electrically programmable devices.

Test equipment and instrument repair services test and repair industrial equipment and instruments. They specialize in the test and repair of acoustic and vibration equipment, electrical and electronic test equipment, laboratory equipment and instruments, inspection instruments or non-destructive testing (NDT) equipment, or specialty testing equipment and instruments.

Online directories list companies on web sites that focus on specific industries or segments. Search engines provide targeted web results based on keywords and other advanced criteria.
