5.5 HiD 2031/2032
Functional description
Repeats a 4-20 mA input signal from a control system to drive I/P converters, electrovalve actuators and displays
located in a Hazardous Area. Each isolated channel has a low input impedance and allows complete freedom of
connection in the input loop due to the high common mode compliance with respect to the supply.
A field open circuit presents a high impedance to the control device input to allow alarm conditions to be
monitored.
Model 2031 Model 2032
Application Guidelines
The barrier is suitable to drive I/P converters or similar current driven device in Hazardous Area. Due to the totally
isolation and low voltage drop-out inputs, the unit HiD 2032 is suitable to perform a single input-dual outputs
connection with an external cross wire as shown in figure
A field open circuit presents a high impedance to the control device input to allow alarm conditions to be
monitored.
The unit can be used with all Elcon standard termination board
