Product Description
2.1
Function
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 device is loop powered, so the available energy at the output is received from
the input signal. The output signal has a resistive characteristic. As a result the
output voltage and current are dependent on the load and the input voltage
At full load, 12 V at 45 mA is available for the hazardous area application.
This device mounts on a HiC Termination Board.
