Pepperl+Fuchs KFD2-HMM-16 HART MUX Primary Module Digital Input 24 VDC
Core Advantages
• High Integration: 16 channels per slot, each supporting dry
contacts or Namur sensors, saving over 30% of cabinet space.
• Hot-Swap Design: Supports online module replacement without
interrupting system operation, reducing maintenance time by 80%.
• Intelligent Diagnostics: Integrated short circuit, disconnection,
sensor failure, and power supply monitoring, with real-time fault
information reported via LEDs and the bus, reducing on-site
inspection workload by 50%.
• Flexible Power Supply: 24 V DC wide-range input with built-in
reverse polarity protection and typical power consumption below 4
W, ensuring energy-efficient operation.
• Seamless Compatibility: Shares the same backplane with all P+F
H-System I/O cards, eliminating the need for additional wiring for
future expansion.
Typical Applications
The KFD2-HMM-16 has been proven in hundreds of oil and gas
processing platforms, LNG receiving terminals, fine chemical
plants, and pharmaceutical plants worldwide. It is commonly used to
collect signals from limit switches, valve feedback, vibration
sensors, and emergency stop buttons, and quickly transmits this
data to a DCS/PLC via PROFIBUS-DP or Modbus-RTU, enabling
interlocking protection, equipment condition monitoring, and
predictive maintenance.
Installation and Maintenance Tips
To install, simply slide the module into the H-System backplane
until the latch clicks into place. 24 V DC and field signal cables
are connected via spring terminals, requiring no special tools.
Sixteen bi-color LEDs on the front of the module provide
easy-to-understand channel status. Integrated replaceable fuses on
the back allow field maintenance to be completed in under two
minutes. It is recommended to perform online diagnostics every six
months using the free P+F PACTware software and save the log for
future review.
