3. Key Features

A. High-Density I/O

• 112 discrete inputs (24 V DC, sink/source selectable)

• 96 discrete outputs (24 V DC, 0.5 A per point, short-circuit protected)

• 200% terminal block support (accommodates extensive wiring)

B. System Integration

• CN61 high-speed bus to FC500 (10 Mbps)

• Dual socket design for expanded connectivity

• Full compatibility with FC500/FC510/FC520 and FC6xx motion boards

C. Industrial Reliability

• Surge protection on all I/O lines

• LED status indicators for power, bus, and I/O activity

• Compact, durable PCB (FR4 material, six-layer design)

4. System Configuration

Mandatory Boards

• CPU: FC250 / FC251

• PLC Core: FC500 (required)

• Backplane: FC001 (min. 3 full slots)

Typical Setup

• High-I/O machining center: FC251 + FC500 + FC800 + FC620 (motion)

• Multi-station automation lathe: FC250 + FC500 + FC800 ×1 + FC430 (128 I/O)

Limitations

• Max 2 × FC800 per system (total 416 I/O points)

• Occupies 1 full slot; cannot coexist with some FC4xx I/O boards

5. Common Faults & Alarms

• I/O Bus Error: CN61 loose connection, FC500 communication fault

• Output Short Circuit: Overloaded output point, damaged transistor array

• Input Signal Drift: 24 V power supply instability, loose wiring

• No LED: 24 V power loss, internal fuse blown, backplane contact issue

6. Applications

• High-I/O CNC machines (5–6-axis, multiple peripherals)

• Multi-station automated production lines (3+ workstations)

• Machine tools with extensive auxiliary functions (coolant, lubrication, tool changers)

• I80 system upgrades for increased PLC I/O capacity
