Pepperl+Fuchs KFD2-HMM-16 HART MUX Primary Module Digital Input 24 VDC 16 Channels

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.
