Product Description
2.1
Function
General
This isolated barrier is used for intrinsic safety applications.
The device supplies power to solenoids, LEDs and audible alarms located in
a hazardous area.
The output signal has a resistive characteristic. As a result the output voltage and current
are dependent on the load.
Line fault detection of the field circuit is indicated by a red LED and an output on the fault bus.
HiD2872
This device is a 2-channel device.
The device is loop powered or bus powered.
It is controlled with a loop powered control signal, switch contact, transistor, or logic signal.
At full load, 12 V at 40 mA (with 55 mA current limit) is available for the hazardous
area application.
An alternative low current output is available for driving a single LED without installing
an external current limiting resistor.
This device mounts on a HiD Termination Board.
HiC2873
This device is a 1-channel device.
The device is loop powered or bus powered.
It is controlled with a loop powered control signal, switch contact, transistor, or logic signal.
At full load, 12 V at 40 mA (with 55 mA current limit) is available for the hazardous
area application.
This device mounts on a HiC termination board.
