The MAMAC Systems EP-313-315 is a precision electropneumatic transducer engineered for demanding building automation and HVAC control applications. It converts an electronic control signal into a proportional pneumatic output, bridging electronic control systems with pneumatically actuated devices such as dampers, valves, and actuators.
Key Features
- Pneumatic output range: 3–15 PSIG for broad compatibility with standard pneumatic control systems
- Supply voltage: 18–28 Vac/Vdc — accommodates a wide range of control panel power supplies
- Field-selectable input signal: choose from 4–20 mA, 0–5 Vdc, or 0–10 Vdc to match your existing control wiring without additional hardware
- Manual override: allows technicians to manually position pneumatic output for commissioning, testing, or emergency operation
- Compact, panel-ready design suited for installation in mechanical rooms and control enclosures
