KFU8-UFC-EX1.D, Frequency Converter with Trip Values
Frequency Converter with Trip Values KFU8-UFC-Ex1.D 1-channel isolated barrier Universal usage at different power supplies Input for NAMUR sensors or dry contacts Input frequency 1 mHz ... 5 kHz Current output 0/4 mA ... 20 mA Relay contact and transistor output Start-up override Line fault detection (LFD) Up to SIL 2 acc. to IEC/EN 61508 / IEC/EN 61511 This isolated barrier is used for intrinsic safety applications.The device is a universal frequency converter that changes a digital input signal into a proportional free adjustable 0/4 mA ... 20 mA analog output signal and functions as a switch amplifier and a trip alarm.The functions of the switch 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 easily configured by the use of keypad or with the PACTware configuration software.A fault is signalized by LEDs acc. to NAMUR NE44.
