1.3 Product Description
The Modutronic 20 IITM is a solid-state integrated circuit-based controller. It is used to operate elec-
tric 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.
1.4 Product Features
Accuracy and repeatability of positioning within 1% of full-scale for actuator stroke times greater
than 30 seconds.
Solid state circuitry for longer life and reliable service
4-20 mA command signal
Can be used to control single or three-phase systems
Jumper selectable Lock-in-Last or Fail-Closed configurations if command signal is lost
Five parameters available for adjustment allows actuator/application match
Adjustable ON and OFF motor control timers
LED indicators display signal, power, and control status to simplify calibration and monitor
