MOD – 20 II

The Modutronic 20 II is a solid state-integrated circuit- based controller. It is used to operate electric valve actuators in wastewater, petrochemical, and other industry applications requiring accurate modulation positioning. The standard input consists of a 4-20 mA signal generated by a process controller; the resulting output is used to accurately and repeatably position a valve actuator through conventional or solid state switching of either single or three-phase AC power. Accuracy and repeat ability of positioning within 1% of full scale for actuator stroke times > 30 seconds.
