Construction

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 com bin ed erro r s ignal v ia Po-

wer Rail

The transformer isolated barrier transfers

digital signals from the hazardous area. Sen-

sors 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 f lashing LED. Fo r

type KFD2-SR2-Ex2.W, an LB/SC combined

error signal 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 DIN VDE 0106

Part 101. Relay outputs are galvanically

separated from each other in accordance

with DIN EN 50178.

Function

Output: Relay

Power Rail PR 05

Power Rail UPR 05

Power feed module KFD2-EB2

The devices are supplied with 24 V DC due to the power feed module KFD2-EB2 and via the Power Rail PR 05 or UPR 05, simultaneously the

combined fault indication will be evaluated.

Each power feed module serves the fusing and monitoring of groups with up to 100 single devices. The PR 05 Power Rail is an inset component

for the DIN rail. The UPR 05 Power Rail is a complete unit consisting of the electrical insert and an aluminum 35 x 15 x 2000 mm DIN rail.

Devices are simply snapped onto it for an electrical connection.

Without the use of a Power Rail, the power supply to the device is directly through the device terminals.
