MAMAC Systems EP-313-315 Electropneumatic Transducer

The MAMAC Systems EP-313-315 Electropneumatic Transducer is a critical component for contractors requiring precise electro-pneumatic conversion in complex BAS and HVACR environments. This 3-15 PSIG I/P transducer utilizes a high-performance, solid-state piezoresistive silicon pressure sensor, providing a 1% full-scale accuracy that holds up in high-demand industrial loops. Designed for maximum field flexibility, it features field-selectable 4-20mA, 0-5Vdc, or 0-10Vdc input signals, allowing you to standardize on one part for multiple controller types. The 18-28 VAC/VDC supply voltage and high airflow capacity ensure rapid response times for pneumatic actuators and dampers. With its compact DIN rail mount footprint—the smallest in the industry—it fits easily into crowded control panels. Built-in short circuit and reverse polarity protection combined with a manual override toggle ensure reliable commissioning and simplified troubleshooting during system balancing.

Key Benefits for HVACR Contractors:

• Universal Input Compatibility: Supports 4-20mA to 3-15 PSIG, 0-5Vdc, and 0-10Vdc configurations to work with any analog output controller.
• Manual Override Capability: Allows for direct manual control and system testing without requiring a signal from the front-end.
• High Precision Performance: Employs piezoresistive silicon sensing technology to maintain linear output and eliminate hysteresis issues common in older mechanical units.
• Simplified Installation: DIN rail mounting and a compact form factor save significant space in sub-panels and enclosures.
• Rugged Protection: Inputs and outputs are electrically protected against wiring errors, preventing board damage during field installation.

Common Questions:

How do I change the input signal type?
The MAMAC EP-313-315 features internal dip switches or jumpers that allow you to toggle between current (4-20mA) and voltage (0-5/0-10Vdc) settings instantly on-site.

Can this transducer handle moist air?
This unit is designed for clean, dry air or inert gases. To prevent fouling the precision silicon sensor, ensure your pneumatic lines are equipped with proper filtration and refrigerated dryers.

What is the maximum supply current required?
The unit draws a nominal 150 mA, making it compatible with most standard 24V building automation system transformers.
