The H COMM Module enables communication between the 9900 and a HART®-enabled device. The HART (Highway Addressable Remote Transducer) Protocol superimposes digital signals on top of the 4 to 20 mA analog signal.
NOTE: With H COMM Module installed, a minimum of 24 V is required for loop-powered systems
