Product Description
2.1
Function
General
Each input controls a relay contact output.
Via switches the mode of operation can be reversed and the line fault detection
can be switched off.
A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error
message output.
If the device is operated via Power Rail, additionally a collective error message is
available.
The device is mounted on a 35 mm DIN mounting rail according to EN 60715.
KFD2-SR3-2.2S
This signal conditioner provides the galvanic isolation between field circuits and
control circuits.
The device transfers digital signals (NAMUR sensors or dry contacts) from the
field to the control system.
KFD2-SR3-Ex2.2S
This isolated barrier is used for intrinsic safety applications.
The device transfers digital signals (NAMUR sensors or dry contacts) from a
hazardous area to a safe area.
2.2
Interfaces
The device has the following interfaces:
• Safety relevant interfaces: input I, input II, output I, output II
• Non-safety relevant interfaces: collective error message output
Note!
For corresponding connections see datasheet.
