New! USB-to-USB Isolator

Protect your PC and USB devices

This small, industrial- grade isolator is very easy to use and provides a high-voltage barrier to protect against surges, noise, and ground loop errors.

Transmitters and Converters

Process transmitters isolate, filter amplify, and convert sensor signals to 4-20mA current or 0-10V voltage signals for interfacing with controllers and other instrumentation. Select from 2-wire loop-powered 4-20mA transmitters, 3-wire DC-powered transmitters, or 4-wire AC/DC-powered transmitters. 3-wire and 4-wire models are available as 4-20mA transmitters or voltage transmitters. DIN-rail and field-mount version are available. Configuration is easy with Windows software, push-buttons, switches, or pots for span/zero settings depending on the series.
