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.
It 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.
2.2
Interfaces
The device has the following interfaces.
•
Safety relevant interfaces: input 1, input 2, output 1, and output 2
•
Non-safety relevant interfaces: none
Note
For corresponding connections see datasheet.
