The transformer isolated barrier
transfers digital signals from the
hazardous area. Sensors per
DIN EN 60947-5-6 (NAMUR) and
mechanical contacts may be used as
alarms. Control circuits are monitored
for lead breakage (LB) and short circuit
(SC). The external faults are indicated
according to NAMUR NE44 by a red
flashing LED. For type KFD2-SR2-
Ex1.W, an LB/SC collective error
message is in addition transferred
through the Power Rail to the power
feed module. The intrinsically safe input
is per DIN EN 50020 safely isolated
from the output and the power supply.
The relay output is in accordance with
IEC 61140 safely isolated from the
power supply.
