Johnson Controls T-5312-1 Controller

Professional-grade climate control in pneumatic transmission systems requires the precision of the Johnson Controls T-5312-1 Proportional Pneumatic Receiver Controller. Engineered for zero-lag performance, this unit interprets a 3 to 15 psig input signal from remote transmitters to manage dampers and valves with industrial accuracy. As a versatile field instrument, the T-5312-1 supports both direct acting (DA) and reverse acting (RA) configurations, which are easily toggled via a clearly marked internal rail. The integration of flexure levers is a critical design feature, effectively eliminating the common mechanical friction and hysteresis that can plague older pneumatic setups. This ensures the output pressure remains responsive and consistent under varying loads. The surface mounting design allows for streamlined installation on local panels, while the integral gauge and set point dial remain visible through the protective cover for rapid diagnostic checks. Built to withstand standard shop vibration, the T-5312-1 is the veteran technician’s choice for reliable pneumatic control and proportional signaling.

Key Benefits

• Dual-Action Versatility: Field-selectable direct or reverse acting modes to match specific actuator requirements.
• Reduced Mechanical Wear: Advanced flexure lever technology reduces friction and hysteresis for smoother control loops.
• Rapid Diagnostics: Features an integral 0 to 30 psig output gauge for real-time pressure monitoring without external tools.
• Simplified Calibration: Designed with an adjustable gain sliding leakport for fine-tuning proportional response in the field.
• Rugged Enclosure: Durable construction suitable for surface mounting in high-vibration mechanical rooms.

Common Questions

How do I switch between direct and reverse action on this controller?
Technicians can switch modes by loosening the slider screw and repositioning the sliding control port along the marked rail inside the unit. Moving the slider to the "DA" position sets it to Direct Acting, while the "RA" position configures it for Reverse Acting.

What is the typical input range for the T-5312-1?
This receiver-controller is calibrated to receive a standard 3 to 15 psig signal from a remote pneumatic transmitter, ensuring compatibility with most legacy and modern pneumatic HVAC systems.

Can the output gauge be replaced if it becomes damaged?
The G-2010-5 output gauge is a standard 1-1/2 inch component that can be replaced on most models; however, note that gauges on units manufactured prior to 1985 were often integrated and may not be field-replaceable.
