1. General Description

2. Basic Specifications

• Applicable system: YASNAC I80 / I80M (requires FC250/FC251 CPU board)

• Backplane: JANCD‑FC001 (standard I80 backplane, 1 full slot)

• Board size: Full‑length (≈267 × 140 mm, same as FC410/FC420)

• Power supply: DC 24V ±10%, approx. 1.8 A

• Operating temperature: 0 to +45°C

• Storage temperature: −20 to +60°C

• Revision: Final revision A01

3. I/O Configuration (Ultra‑High‑Density)

Inputs (IN): 128 points

• Signal level: DC 24V, sink/source selectable (NPN/PNP compatible)

• Usage: Limit switches, proximity sensors, pushbuttons, E‑stop, tool sensors, clamps, pallets, safety doors

• Response time: ≤0.8 ms (high‑speed sampling)

Outputs (OUT): 128 points (transistor)

• Voltage: DC 24V, max 0.5 A per point

• Usage: Solenoids, relays, indicators, alarms, cylinders, motor start signals, valve banks

• Protection: Self‑resetting fuse per point, overload/short‑circuit protection, surge suppression

Connectors

• CN43: I/O terminal block (128IN / 128OUT, screw terminals, 4 rows)

• CN20: System bus (to backplane, high‑speed communication with FC250/FC251)

• LEDs: Power, bus status, IN/OUT channel status, fault diagnostics

5. System Compatibility & Combinations

Mandatory pairing

• CPU board: JANCD‑FC251 (high‑grade) (FC250 not recommended due to bus load)

• Backplane: JANCD‑FC001

Recommended configurations

• Ultra‑high‑density setup: FC251 + 1×FC430 (max I/O for I80: 128IN/128OUT)

• Mixed high‑density setup: FC251 + FC430 + FC400 (160IN/160OUT total)

• Axis boards: FC300B (3‑axis feed), FC310 (spindle), FC260 (8‑axis feed)

Limitations

• Cannot be used standalone (depends on FC251 for power and high‑speed bus)

• Occupies 1 full slot on FC001 backplane

• I80 system limit: 1×FC430 maximum (due to maximum bus bandwidth usage)

6. Common Faults & Alarms

• A.430 Bus error: CN20 loose, backplane contact failure, bus chip overload

• No input signals: CN43 wiring loose, 24V supply fault, input channel burnout

• Outputs not activating: Overload/short circuit, load fault, wiring error, surge damage

• All LEDs off: Backplane 24V missing, internal main fuse blown

• Partial channel failure: Terminal block oxidation, bent pins, internal trace damage

7. Applications

• Large 5‑axis/6‑axis machining centers (massive I/O for clamps, pallets, tools, safety)

• Multi‑station transfer lines (high sensor/actuator count for synchronized motion)

• Fully automated production cells (machine + material handling + inspection + robotics)

• High‑end multi‑spindle turn‑mill centers (dual spindle + multiple turrets + B‑axis)

• Legacy system upgrades (max I/O expansion without full CNC replacement for large machines)
