SOR Incorporated 522E1-TC3-P7-C2A Pressure Switch

The SOR Incorporated 522E1-TC3-P7-C2A Pressure Switch operates over a 0-30 psi range and provides dual outputs: a 120 VAC electrical output for switching loads and a 4-20 mA current output for instrumentation or control loops. Identified by the part number 522E1-TC3-P7-C2A, it belongs to SOR’s family of pressure and vacuum switches designed to integrate with control-system architectures that require both a discrete switch signal and an analog current signal. In typical applications, it can monitor process pressure and trigger a circuit at the setpoint while simultaneously feeding a 4-20 mA signal to a controller or display, enabling local control and remote monitoring from a single device. The combination of a defined pressure range with two outputs makes this switch suitable for instrumentation panels, automation racks, and equipment that rely on mains-powered switching alongside continuous process feedback.
