EP3 | No Anlg Out | Alarm | Failsafe | Cvr
Features
- Field-selectable 4-20mA/0-5V/0-10VDC input for application flexibility
- Poppet valve technology for quiet operation
- Manual override with set and hold feature great for commissioning those leaky systems
- Multi-point calibration; 3-15 psi (5 point calibration) & 0-20 psi (6 point calibration)
- Pressure loss alarm provides a contact closure if the EP3 is unable to achieve the desired output within a fixed length of time
- Failsafe vent solenoids bleed branch pressure on power failure for added safety
- Optional transparent plastic dust cover (AA43) protects units from dust and tampering (required for CE)
- User programmable zero and full scale outputs
- Backlit LCD for local indication of readings easy to view
- Dual-color LED assists in trouble shooting
- Tri-State and PWM inputs
Description
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 and optional covers are available.
Application
- Hospitals
- Schools
- Pneumatic dampers/actuators
