Johnson Controls P736MCA-9300 dual-signal pressure switch, -0.5 – 7.0 / 3.0 – 30.0 bar, automatic, differential pressure 0.6 – 3.0 bar, 1/4" SAE flare

The Johnson Controls P736MCA-9300 is a high-precision dual-signal pressure switch specifically designed for simultaneous monitoring of low- and high-pressure zones in commercial and industrial refrigeration systems. The device offers two separate switching zones:

• Low pressure range: -0.5 to 7.0 bar

• High pressure range: 3.0 to 30.0 bar

The automatically resetting pressure switch allows an adjustable differential of 0.6 to 3.0 bar , ensuring precise control of the system pressure. The dual-signal function (two electrical outputs) makes it particularly suitable for applications requiring both control and safety shutdown.

Thanks to the 1/4" SAE flare connection, the device can be easily and reliably integrated into existing piping systems. The robust construction ensures a long service life, even under demanding conditions – perfect for HVAC systems, heat pumps, and commercial refrigeration systems .
