Large capability in a small package

Like it's bigger sibling, the ESX®-LT from Sensor-Technik Wiedemann (STW) is designed to do harsh control jobs and do them well. Each ESX®-LT has eight digital inputs, eight multi-function inputs, and eight eight digital or PWM outputs. Each multi-function input is capable of both analog or digital/frequency inputs.
