Johnson Controls EP-8000-1 Transducer

The Johnson Controls EP-8000-1 is a precision electro-pneumatic transducer engineered to convert a proportional electrical signal into a linear pneumatic pressure output. This specific model supports a 0.5 to 9 VDC input range and delivers a 1 to 18 psig output. Unlike higher-capacity relay models, the EP-8000-1 is a low-volume, non-relay transducer, making it ideal for direct terminal unit control and pilot-loading larger volume boosters. The compact design allows for standard DIN rail or surface mounting, facilitating integration into pneumatic control sequences within commercial HVAC systems. Contractors often utilize this unit for interfacing electronic controllers with legacy pneumatic actuators and dampers. By eliminating mechanical linkages, the EP-8000-1 ensures consistent HVAC signal conversion with minimal hysteresis. Its low-air consumption design optimizes system efficiency, while the field-selectable voltage input provides versatility for various BMS integration requirements.

• Precision Signal Conversion: Accurately translates 0.5-9 VDC signals into direct 1-18 psig pneumatic pressure.
• Low Volume Output: Optimized for non-relay applications where minimum air consumption and direct actuation are required.
• Compact Footprint: Designed for easy installation in tight control cabinets using standard mounting brackets.
• System Integration: Essential for hybrid DDC-to-Pneumatic retrofits and building automation upgrades.
• Reliable Performance: Built with industrial-grade components to maintain calibration stability in demanding environments.

Can the EP-8000-1 drive multiple large actuators?
As a non-relay transducer, the EP-8000-1 is designed for low-volume applications. For larger loads or multiple actuators, it should be used to pilot a volume-boosting relay.

What is the primary difference between the EP-8000 and the EP-8000-1?
The difference lies in the input and output calibration ranges; the EP-8000-1 specifically targets the 0.5-9 VDC to 1-18 psig range required by specific Johnson Controls sequences.

How is the unit mounted in a control panel?
The unit features a universal mounting design compatible with 35mm DIN rails or direct surface mounting via screws.
