Johnson Controls P70DA-1C High Pressure Lockout SPST

Johnson Controls P70DA-1C High Pressure Lockout SPST is a single-pole, single-throw safety interlock designed to interrupt a control circuit when system pressure hits a preset high level. As a high-pressure lockout, it provides a reliable means to stop equipment or prevent startup when pressure exceeds safe limits, helping protect compressors, vessels, and piping from damage or hazardous conditions. The device uses SPST contacts to interrupt the circuit in response to a pressure signal, with the P70DA-1C designation identifying this Johnson Controls part. Suitable for systems that require high-pressure protection, this lockout is commonly employed in HVAC and refrigeration installations and other pressurized environments where stopping operation at excessive pressure is critical. By providing a straightforward electrical interlock, the P70DA-1C helps maintain system safety without altering other control logic, making it a practical choice for safety interlocks in complex mechanical systems.
