5.7 HiD 2035/2036
Functional description
Interface Fire and Smoke detectors, or similar switched resistor system requiring a wide output current range from
1.5 to 50 mA, located in a Hazardous Area. Also 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. Designed for high integrity
applications, each channel is loop powered with a low voltage drop and permits detection of line faults, by the
control system.
A field open circuit presents a high impedance to the control device input to allow alarm conditions to be
monitored.
Model 2035 Model 2036
Application Guidelines
As any other loop powered isolator, the HiD 2035/HiD 2036 has a fail safe behaviour, i.e. if there is a loop supply
fault, the isolator output is de-activated.
The two HiD 2036 channels are completely isolated one each other. This means that single-loop integrity is
preserved also with the two-channels version.
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
