Veris EP3031S2 : Electropneumatic Transducer, Selectable 4 to 20mA/0-5V/0-10 VDC, Tri-State, PWM Control Input, 0 to 25 psi Control Output, Pressure Loss or Manual Mode Alarm, No Analog Output, Vent on Power Fail, EP Cover Plate
The EP3 series combines a microcontroller with high performance, low power coil poppet valve technology to create a system with unparalleled accuracy and proven reliability. The poppet valves used in the EP3 consume no air, eliminating unnecessary air losses in the system and allowing for efficient, long-term operation. The EP3 permits versatility, since all models feature manual override and a tri-state control option. The LCD provides easy visibility and the LED indicators provide visual status of valve operation in manual or automatic mode. All models come with SnapTrack housing.
- Poppet valve technology for quiet operation
- Manual override with set and hold feature, great for commissioning leaky systems
- Pressure loss alarm provides a contact closure if the EP3 is unable to achieve the desired output within a fixed length of time
- Media connection - clean, dry air, or inert gas, do not use with oxygen service
