Loop powered devices are modules and computer boards which are powered by the system they serve.

Signal isolators must be used when connecting grounded signal sources to grounded signal followers.

Signal conditioner chips are data acquisition devices that refine sensor outputs so that they can be read by computer boards or other IC devices.

Current loop converters convert an analog or digital signal to a current loop output such as 4-20 mA or 0-20 mA

Optical isolators are optical devices that allow light to be transmitted in only one direction.

DC powered pumps use direct current from motor, battery, or solar power to move liquids such as acids, chemicals, lubricants and oil, as well as water, wastewater, and potable water

Hook and loop fasteners consist of two layers of fabric.
