Description
The MAMAC Systems EP-311-020 is a precision-engineered electropneumatic transducer designed for reliable electronic-to-pneumatic signal conversion in commercial and industrial HVAC control systems. With a 0–20 PSIG output pressure range, this transducer accurately translates electronic control signals into proportional pneumatic output, making it an ideal interface between modern DDC/BAS controllers and legacy or current pneumatic actuators and devices.
Key Features
- Output pressure range: 0–20 PSIG for broad pneumatic system compatibility
- Supply voltage: 18–28Vac/Vdc for flexible power source integration
- Field-selectable input signal: choose from 4–20mA, 0–5Vdc, or 0–10Vdc to match your control system output
- No manual override — ideal for applications where operator-initiated pneumatic adjustment is not required
- Compact, field-ready design suited for panel or direct-mount installation
Signal Flexibility
The EP-311-020’s field-selectable input allows technicians to configure the transducer on-site to accept the most common electronic control signals — 4–20mA, 0–5Vdc, or 0–10Vdc — without the need for additional signal conditioning hardware. This versatility simplifies integration with a wide range of building automation systems and DDC controllers.
Typical Applications
- Pneumatic valve and damper actuator control
- DDC-to-pneumatic system interface
- VAV box and air handling unit control
- Commercial building automation and energy management systems
