Hart - RS485 Converter

HMT-112, HART to MODBUS Converter is designed to accept HART inputs from maximum 15 slave units and convert standard variables into fixed MODBUS address registers. This is useful to accept / read exact values available for Flow, Pressure, Temperature transmitters in digital form in the control room eliminating errors in Analog input acquisition and process systems. User selectable baud rate for MODBUS Master on DIP switch is provided. LED Indications for master and slave operations for easy diagnosis.
