The Pepperl+Fuchs KFD2-SLD-Ex1.13100 serves as the primary KFD2-SLD Solenoid Driver utilized to execute intrinsically safe loop energization for field-mounted valves across intrinsic safety (Ex i) barriers platforms.

Model Designation & Suffix Logic

• KFD2: K-System standard housing designed for 35 mm DIN rail or Power Rail installation.
• SLD: Solenoid driver function group delivering loop-powered or bus-powered drive current.
• Ex1: Single-channel galvanically isolated intrinsically safe output circuit.
• 13100: Specific voltage/current output characteristic profile (13 V DC output voltage limit at 100 mA current threshold).

Core Technical Specifications

Hazardous Area Barrier Integrity and Mechanical Stability

The isolated driver channels preserve strict intrinsic safety (Ex i) barriers separation between safe-area logic controllers and hazardous area field actuators. Solid housing latches enforce high DIN-rail mounting stability under ambient mechanical stress, preventing earth loops while maintaining internal surge voltage protection limits and low protocol conversion latencies across field discrete actuation loops.

Field Installation & Wiring Protocol

Module Rail Placement

Attach the module vertically onto a standard 35 mm DIN rail or integrated Power Rail structure. Press down firmly until the locking spring latches engage with the rail profile.

Safe Area Control Signal Wiring

Terminate logic switching signals from the host controller at black terminals 7(+) and 8(-). Ensure drive signal levels strictly match the specified 24 VDC control threshold.

Hazardous Field Actuator Connection

Connect field solenoid wires to blue terminals 1(+) and 2(-). Maintain physical routing separation between intrinsically safe field wiring and non-intrinsically safe power lines.

Frequently Asked Questions

• What maximum output drive current does the module supply to a field solenoid valve?

  The driver supplies up to 100 mA continuous current at a minimum output voltage of 13 VDC to actuate field solenoids.

• Is an external auxiliary power supply required to operate this driver channel?

  The driver loop operates directly from the 24 VDC control input signal, eliminating the need for a separate auxiliary power connection.

• What happens to the hazardous area output if the safe-area control signal drops?

  When control voltage drops below threshold level, output current collapses immediately to zero, returning the field valve to its safe de-energized position.

• Does the device support line fault transparency for field cable break detection?

  Line fault monitoring detects open-circuit or short-circuit conditions on field lines and mirrors the fault status back to the control system.

• How is electrical separation maintained between the logic input and field output?

  Galvanic isolation rated at 2.5 kV AC prevents potential surges from propagating between safe-area control logic and hazardous field wiring.

• What maximum wire cross-section can be terminated into the pluggable terminals?

  Pluggable terminal blocks accept solid or stranded copper conductors up to a maximum cross-sectional area of 2.5 mm square.

• Can the driver be mounted horizontally inside a crowded control cabinet?

  Vertical DIN-rail mounting is recommended to optimize convection airflow and ensure operation within specified ambient thermal limits.

• How does the unit protect against field wiring short circuits?

  Internal current-limiting electronics clamp output current to safe levels during field short-circuits, preventing module damage or thermal hazards.
