Function: KFD2-FF-Ex2.RS232

This isolated barrier is used for intrinsic safety applications. It is a repeater for the bi-directional transfer of RS 232 signals.

The input and output circuits are intrinsically safe and designed to transmit and receive RS 232 signals between the safe area and the hazardous area.

This barrier accepts input signals in the ±3 V ... ±15 V range providing a nominal ±10 V output that is independent of the input voltage.

The maximum rate of data exchange is 20 kBits per second.
