Product Description
"KFD2-UFC-Ex1.
D trip values One-channel isolated barrier 24 V DC supply (power rail) Input for NAMUR sensors or mechanical contacts Input frequency 1 mHz - 5 kHz Current output 0/4 mA - 20 mA Relay contact and transistor output Startup override Line fault monitoring Up to SIL 2 in accordance with IEC/EN 61508 / IEC/EN 615This isolated barrier is suitable for intrinsically safe applications.
The device is a universal frequency converter that changes a binary input signal into a proportional, freely adjustable analogue 0/4 mA to 20 mA output signal and functions as a switching amplifier and trip alarm.
The functions of the switching outputs (2 relay outputs and 1 potential-free transistor output) are easily adjustable [trip value display (min/max alarm), serially switched output, pulse divider output, error signal output].
The device is configured using the keypad or via PACTware configuration software.
An error is indicated by LEDs in accordance with NAMUR NE44 and is output via a separate collective error message"
