Included with each device
- Valve close override and valve open override: Utilize alarms to quickly vent your system or stop all flow as needed.
- Monochrome backlit LCD with integrated touchpad: Easily read measurements using the backlit display and control configurations with the user-friendly integrated touchpad.
- Autotune: Automatically improve the control performance of the valve and tune the control parameters of the device for your application.
- User-adjustable setpoint ramping & limits: Configurable ramp rates allow the process variable to be controlled as fast or as slow as desired, and configurable setpoint limits protect processes from inadvertent setpoint changes.
- User-adjustable standard temperature and pressure (STP) conditions: Quickly change reference conditions without the need for recalibration.
