Description

Description

Pepperl+Fuchs Switch Amplifier KFD2-SR2-Ex2.W 203355 

This isolated barrier is used for intrinsically safe applications.

The device transfers digital signals from NAMUR sensors or dry contacts from the hazardous area to the non-hazardous area.

The proximity sensor or mechanical contact controls the control side load for an output with relay contact. The output of the device changes state when the input signal changes state.

Using the switches it is possible to invert the operating mode and deactivate line fault detection.

During a fault condition fault, the relay returns to the de-energized state and the LEDs indicate the fault according to NAMUR NE 44.

If the device is operated via Power Rail a collective error message is also available.

Isolated barrier 2-channel, 24 V DC power supply (power rail), dry contact or NAMUR inputs, relay contact output, line fault detection (LFD), reversible operating mode, up to SIL 2 (SC 3) acc. according to IEC/EN 61508, housing width: 20 mm, number of channels: 2 channels, safety integrity level (SIL): SIL 2, systematic capacitance (SC): SC 3, nominal voltage: 19 ... 30 V DC , Field device: NAMUR sensor, Field device [2]: potential-free contact, Line fault detection, Type: 2 x relay (changeover contact)

Connection: power rail or 14+ terminals, 15-
Rated voltage: 19 ... 30 V DC
Ripple: ≤ 10%
Rated current: ≤ 50 mA
Power dissipation: ≤ 1 W
Power consumption: ≤ 1 W
