Frequency Converter with Trip Values
KFD2-UFC-Ex1.D
- 1-channel isolated barrier
- 24 V DC supply (Power Rail)
- 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 61508/IEC 61511
Function
- 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 and a separate collective error message output.
- For additional information, refer to the manual and www.pepperl-fuchs.com.
