I. Basic Information

Compatible System: YASNAC I80 / I80M (must be paired with FC250/FC251 mainboard)

Assembly Backplate: JANCD-FC001 (standard backplate for I80, single slot)

Board Size: Full-length board (approximately 267×140mm, same as FC310)

Weight: Approximately 1.6 kg

Power Supply: DC 24V ±10%, approximately 1.2A

Version: FC410 (Rev.A02 is the final version)

II. Core Specifications (I/O Points: 64IN/64OUT)

1. Input (IN): 64 points

Voltage: DC 24V, NPN/PNP compatible (sink/source optional)

Purpose: Limit switches, proximity switches, buttons, emergency stop, tools, fixtures, tray signals, etc.

Response Time: ≤1ms, high-speed signal acquisition

2. Output (OUT): 64 points (transistors)

Voltage: DC 24V, maximum load 0.5A / point

Purpose: Electromagnetic valves, relays, indicator lights, alarm lights, cylinders, motor start signals, etc.

Protection: Each point has self-recovery fuse, overload / short-circuit protection

3. Interfaces

CN41: I/O terminal block (64IN/64OUT, screw connection, divided into upper and lower rows)

CN20: System parallel bus (connected to the backplate, communicates with FC250/FC251)

LED: Power, bus, input/output status lights, fault rapid diagnosis

III. FC410 vs FC400 (Expansion Board vs Standard Board) Table

Comparison item FC410 (Extended I/O Board) FC400 (Standard I/O Board)

I/O points 64IN / 64OUT 32IN / 32OUT

Board size Full-length board (267mm) Semi-length board (235mm)

I/O density High, suitable for complex equipment Medium, suitable for standard machine tools

Combination limit Up to 2 FC410 boards Up to 2 FC400 boards

Typical pairing FC251 (High-end Controller) + FC410 FC250 (Standard Controller) + FC400

Application scenarios Large machining centers, turning-milling combination, automated lines Ordinary lathes, small machining centers

IV. Compatibility and Pairing (Required Combinations)

✅ Basic expansion configuration (most commonly used)

Controller board: JANCD-FC251 (High-end, supports more I/O)

I/O board: FC400 + FC410 (Total 96IN/96OUT, meets large equipment requirements)

Feed / Spindle board: FC300B (3-axis feed), FC310 (spindle)

Backboard: JANCD-FC001

✅ Full high-end configuration

Main controller: FC251

I/O: 2 FC410 boards (128IN/128OUT, large point count)

Feed: FC260 (8-axis)

Spindle: 2 FC310 boards (dual spindles)

✅ Key limitations

Cannot be used alone: Must rely on FC250/FC251 for power supply and communication

Slot occupation: Full-length board, occupies 1 backboard slot (same as FC310)

System limit: I80 can support up to 2 I/O boards (FC400/FC410 combination)

V. Common Faults

A. 410 bus error: CN20 backboard contact failure, bus chip failure

No input signal: CN41 wiring loose, 24V power supply abnormal, input point burned out

Output does not act: Output point overload burned out, load short circuit, wiring error

All LEDs off: Backboard 24V power supply missing, internal fuse blown

Partial points no response: Terminal block oxidation, pin deformation, internal circuit break

VI. Application scenarios

Large I80 machining center: 4-axis / 5-axis linkage, requires a large number of fixture, tray, and tool signals

Turning-milling combination machine: Dual spindles + multiple station tool tower, I/O requirements are dense

Automated production line: Machine + loading-unloading mechanism, conveyor belt, inspection equipment linkage

Renovation of old machines: Replace aging I/O boards, expand point count to adapt to new functions

Special machine tools: Multi-station drilling and tapping machine, combined machine tools, non-standard automation equipment
