Honeywell TK-FFSU01 51309582-275 Power Supply Boards
The Honeywell TK-FFSU01 51309582-275, also cataloged as the TK-FFSU01 Power Supply Board, operates as a dedicated hardware component for low-voltage DC power delivery within Honeywell C200 and C300 control systems. This power supply board converts 240 VAC input utility power into a regulated 5 VDC output rail capable of delivering up to 2 A continuously to adjacent system microprocessors and I/O cards. Occupying a compact 12.7 x 3.8 x 19.1 cm profile, the board provides stable electrical rails required for deterministic system execution across industrial temperature ranges from -10 to 50 deg C.

Process Control & DCS Power Architecture
The power supply board regulates DC voltage rails across C200 and C300 system racks while maintaining input-to-output electrical isolation. Internal voltage regulation circuitry compensates for line fluctuations, preventing power dropouts from corrupting 4-20 mA HART loop protocol communications or digital I/O processing routines. High-grade thermal dissipation components maintain voltage stability across ambient cabinet temperature swings, protecting internal control logic against ripple voltage and overcurrent conditions.
Frequently Asked Questions
Q: Does the board support hot-swapping while the C200/C300 rack is powered?
A: Technicians must de-energize the 240 VAC input line prior to removing or installing the board to prevent arc flash risks and voltage surges on the 5 VDC system bus.
Q: How does the power supply handle output current overloads exceeding 2 A?
A: Internal current-limiting protection circuits clamp the output voltage if load demand exceeds 2 A, preventing permanent component damage during field short-circuit conditions.
Field Installation Guidelines
Verify that the 240 VAC primary feeder circuit is fully de-energized and locked out before wiring input terminals. Secure the board firmly onto the mounting slot using designated chassis screws to ensure proper grounding and mechanical stability. Route incoming AC power lines away from low-voltage DC signals and communication cables by maintaining at least 300 mm clearance to eliminate line noise. Connect the enclosure earth terminal directly to the main cabinet ground bar using a short, low-impedance copper strap before re-energizing the unit.
