Solenoid Control Interface
The Solenoid Control Interface (SCI) allows the Eagle XA Series products to perform remote control of pressure or flow.

Description
An Existing gas regulator can be converted to remote control pressure or flow without requiring any process piping modifications. Only some instrument tubing and regulators are required for the interface to the SCI.
The SCI is designed to operate self contained or pilot operated pressure regulators. It can also be used to control diaphragm actuated instruments valves.
- Intrinsically safe – when using IS barriers
- Low Power – 24V with IS barriers, 12V without
- Requires no power when not making adjustments
- On power failure, SCI blocks in the loading pressure at last position
- Mechanical spring in wither the process or pilot regulator sets the low operating pressure limit.
- Quick response to load changes, with mechanical regulator or pilot responding
- Venting only occurs during unloading control process unlike continuous bleeding when using traditional I/P transmitters.
- (2) Pulse Inputs for Dual Meter Configurations
