Industrial A410211 Digital Differential Pressure Controller

The Sensocon A410211 is a 0.25% accuracy digital differential pressure controller from the Series A4 family, designed to monitor and control differential pressure in HVAC, cleanroom, and industrial air systems. It combines an OLED programming display for configuration with a live 4‑digit red LED readout to show current differential pressure and setpoint status. The unit includes two 8A SPDT relays for direct control of fans, dampers, or other actuators, and uses push‑on connections for 3/16" tubing on the process ports. The A4102 variant—the 0.25% accuracy option—can also be configured to provide a 4‑20 mA output when used as a digital indicating transmitter, aligning with Sensocon's digital differential pressure gauges and controls for versatile installation options.
