Description
MAMAC Systems EP-311-315 Electropneumatic Transducer Overview
The MAMAC Systems EP-311-315 is a precision electropneumatic (E/P) transducer engineered for commercial and industrial HVAC control applications. It converts an electronic control signal into a proportional pneumatic output, making it an essential interface device between electronic building automation systems and pneumatic actuators, dampers, and valves. With a robust 3-15 PSIG output range and wide-range supply voltage compatibility, this transducer delivers reliable, accurate signal conversion in demanding building automation environments.
Key Features
- Pneumatic output range: 3–15 PSIG for direct compatibility with standard pneumatic control devices
- Supply voltage: 18–28Vac/Vdc — accommodates a wide range of control system power supplies
- Field-selectable input signal: choose from 4–20mA, 0–5Vdc, or 0–10Vdc to match your BAS or controller output
- No manual override — clean, streamlined design for fully automated control applications
- Compact form factor suitable for panel mounting or field installation
- Designed for seamless integration with pneumatic actuators, VAV boxes, dampers, and control valves
Signal Input Options
The EP-311-315 offers three field-selectable input modes, eliminating the need for separate transducer models across different system configurations:
- 4–20mA current loop input
- 0–5Vdc voltage input
- 0–10Vdc voltage input
Typical Applications
- Pneumatic damper actuator control in air handling units
- VAV box pneumatic actuator interface
- Control valve positioning in hydronic heating and cooling systems
- Building automation system (BAS) to pneumatic device signal conversion
- Retrofit of pneumatic systems with electronic controllers
