Duplex II™ Controller

The Duplex™ II Controller is a single or dual-channel controller for Eclipse® Emergency Valve Shutoff Actuators. It allows operators to remotely close up to two chlorine or sulfur dioxide container valves in an emergency. Using Halogen's unique patented Torque-Sense™ technology, the Duplex™ II measures the actual torque applied to each valve stem to provide reliable confirmation of valve closure. Optional relay packages and SCADA outputs can remotely communicate up to 23 different system diagnostics to a PLC or data acquisition system.
