Johnson Controls C-5230-2 Limiter

The Johnson Controls C-5230-2 Pneumatic Signal Limiter is an essential component for precise pneumatic control system management, designed to establish high or low signal limits within a control circuit. Operating on a 13-25 psig supply pressure range, this direct-acting proportional limiter maintains a strict 1:1 ratio between input and output within the defined limits. The high limit adjustment allows for a 3 to 1 psig differential relative to supply pressure, while the low limit adjustment maintains a 2 to 1 psig range. This unit is critical for protecting downstream actuators and terminal equipment from over-pressurization or insufficient signal strength. Built for HVAC pneumatic pressure regulation, the C-5230-2 ensures stable pneumatic signal limiting in complex sequences, preventing hunting and ensuring accurate HVAC control loop performance. Installation is straightforward for technicians, providing a reliable hardware-based constraint for Johnson Controls pneumatic actuators and controllers.

• Precise Signal Constraints: Effectively clamps the output signal to prevent mechanical strain on valves and dampers.
• Direct-Acting Reliability: 1:1 ratio ensures predictable performance across the 13-25 psig operating range.
• Selectable Limit Functions: Configurable for either high or low limit applications depending on the control sequence requirements.
• Industrial Build Quality: Designed to withstand the rigors of mechanical rooms and commercial pneumatic systems.
• Seamless Integration: Compact footprint allows for easy mounting within existing control cabinets.

Does this limiter support reverse-acting sequences?
The C-5230-2 is a direct-acting signal limiter; it is designed to maintain a 1:1 ratio within its set mechanical limits for direct-acting pneumatic loops.

What is the maximum supply pressure for the C-5230-2?
This model is rated for a nominal supply pressure of 13-25 psig. Exceeding these parameters can impact the accuracy of the high and low limit adjustments.

Can I use this for both high and low limit simultaneously?
The unit is specific to the limit set; it functions as a high or low limit signal limiter based on your specific piping and adjustment configuration within the branch line.
