PEPPERL+FUCHS KFD2-SOT-EX2 034065

Pepperl+Fuchs KFD2-SOT-EX2 Switch Amplifier Description The KFD2-SOT-EX2 is a high-reliability, 2-channel switch amplifier from Pepperl+Fuchs’ K-System. This isolated barrier is engineered for intrinsic safety applications, allowing it to safely drive devices like solenoid valves, I/P converters, or LED indicators within a hazardous area. It accepts inputs from NAMUR sensors or dry contacts and provides a galvanically isolated transistor output to the safe area. Key features include line fault detection (LFD) and a reversible mode of operation for maximum flexibility. Specifications Type: Switch Amplifier / Isolated Barrier Channels: 2 Input Signal: NAMUR, dry contact Output Signal: Transistor output Supply Voltage: 20 V DC to 35 V DC Ambient Temperature: -20 to 60 deg C (-4 to 140 deg F) Mounting: DIN Rail Connection: Screw terminals Label Info Part No: 034065 ATEX Certification: PTB 00 ATEX 2080 Safety Marking: II (1) G D [Ex ia] IIC Application Ideal for use in process automation, chemical, petrochemical, and pharmaceutical industries where control signals must be sent into potentially explosive atmospheres. It ensures that the energy level of the signal entering the hazardous area is too low to cause an ignition. Country of Origin Made in Singapore. CO2 Impact By purchasing this reused component, you are contributing to a circular economy and avoiding approximately 6.0 kg of CO2 emissions that would be generated from manufacturing a new one.

FAQ What is the primary function of the KFD2-SOT-EX2 in a control system?Its primary function is to act as an intrinsically safe (IS) isolated barrier. It takes a low-power, non-IS signal from a control system (like a PLC) and converts it into an IS signal that can safely operate a device (like a solenoid valve) in a hazardous (potentially explosive) area without risk of ignition. How do I configure the output mode for normally open (NO) or normally closed (NC) operation?The output mode can be reversed via switches on the side of the unit. This allows you to configure the output to be energized (switched on) or de-energized (switched off) when the input is active, accommodating both NO and NC logic. What does the Line Fault Detection (LFD) feature indicate and how is it enabled?Line Fault Detection monitors the field circuit for open-circuit (wire break) or short-circuit conditions. If a fault is detected, a dedicated LFD output is activated, and a red LED on the front of the unit will blink. This feature is enabled via a switch on the side of the module.
