Product Details

Product Introduction

The HART protocol uses the Bell202 Frequency Shift Keying (FSK) standard to superimpose a modulated digital signal on a 4 to 20 mA basis, allowing the HART protocol instrument to allow bidirectional data communication without interfering with the 4 to 20 mA analog signal. SM100-M series HART data collector is an intelligent converter for bidirectional modulation and demodulation of digital signal and analog signal.
