Description
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
Technical Specifications
- Model: EP-313-315
- Brand: MAMAC Systems
- Pneumatic Output: 3–15 PSIG
- Supply Voltage: 18–28 Vac/Vdc
- Input Signal (field selectable): 4–20 mA, 0–5 Vdc, or 0–10 Vdc

Ideal Applications
- Building automation systems (BAS) interfacing electronic controllers with pneumatic actuators
- VAV box and AHU damper control
- Pneumatic valve positioners in commercial HVAC systems
- Retrofit projects converting electronic signals to pneumatic control
The field-selectable input makes the EP-313-315 exceptionally versatile — a single unit covers the three most common analog control signal types, reducing the need to stock multiple transducer models. The built-in manual override adds convenience during startup and maintenance, giving technicians direct control without disconnecting wiring or removing the device.
