Johnson Controls C-5230-3 Pneumatic Signal Limiter High and Low Limit

The Johnson Controls C-5230-3 is a pneumatic signal limiter designed to restrict control signals to safe operating ranges in HVAC and building automation systems. This Series C-5230 device provides both high and low limit control, preventing pneumatic control signals from exceeding preset thresholds that could damage equipment or compromise system performance.

Key Features:

• Dual limit control restricts both high and low signal ranges
• Pneumatic operation for reliable performance in building automation systems
• Protects downstream equipment from out-of-range control signals
• Compatible with standard pneumatic control systems operating at 3-15 PSI or 8-13 PSI ranges
• Compact design for easy integration into control panels and valve assemblies

Signal limiters are essential safety devices in pneumatic control systems, commonly used with damper actuators, valve operators, and other control devices to prevent over-travel or unsafe operating conditions. The C-5230-3 ensures that control signals remain within acceptable parameters regardless of upstream controller output variations.
