Product Description

Product Specifications

The HART protocol utilizes the Bell202 Frequency Shift Keying (FSK) standard to superimpose a modulated digital signal on top of a 4 to 20 mA base. This allows the HART protocol instrument to facilitate bidirectional data communication without interfering with the 4 to 20 mA analog signal. The SM101 series intelligent converter is designed to modulate and demodulate digital and analog signals in both directions with high precision.
