Composition

24 V DC
• 2-channel

• Control circuit EEx ia IIC

• Reversible mode of operation

• 1 signal output with 1 changeover

contact per channel

• EMC acc. to NAMUR NE 21

• LB/SC monitoring

• LB/SC collective error message via

Power Rail

• Usable up to SIL 2 acc. to IEC 61508

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-
Ex2.W, an LB/SC collective error
message is in addition transferred
through the Power Rail to the power
feed module. The intrinsically safe
inputs per DIN EN 50020 are safely
isolated from the output and the power
supply. Relay outputs are galvanically
separated from the mains power in
accordance with IEC 61140. Relay
outputs are galvanically separated from
each other in accordance with
IEC 61140.
