Core Functions

• High‑Density Isolated I/O: 48/24 channels for general‑purpose machine I/O

• Noise Filtering: Hardware RC filters on all inputs for contact bounce/EMI suppression

• Relay/Solenoid Driving: Direct drive for 24 V DC relays, valves, and indicators

• Status Monitoring: Per‑channel LED indication for fast troubleshooting

• System Interlocking: Critical safety and machine logic interlock signals

• Legacy Compatibility: Drop‑in replacement for original JANCD‑1 boards

Application Scenarios

• YASNAC CNC Machine Tools: Mori Seiki, Mazak, and other CNC mills/turning centers

• Early Motoman Robots: XRC series controllers (material handling, welding)

• Legacy Automation Lines: Retrofit/replacement for 1990s–2000s Yaskawa systems

• General Industrial Control: Packaging, textile, and woodworking machinery

• Harsh Environments: High vibration, dust, and electrical noise shop floors

Compatibility Notes

• Replaces: JANCD‑1, JANCD‑1-0-01 (non‑isolated), JANCD‑1-0-01A

• Compatible With: YASNAC LX3, MX3, FX series; Motoman XRC, NX100 (adapter required)

• Not Compatible With: JANCD‑1001/1001B (different bus & I/O mapping)

Usage & Maintenance

• Wiring: Use shielded twisted‑pair cables for I/O; separate high‑power and signal wires

• Ventilation: Ensure cabinet airflow (0–50 °C); avoid direct heat

• Connectors: Secure ribbon cables to prevent vibration‑induced intermittent contact

• Cleaning: Inspect/clean dust from board and connectors every 6 months

• Testing: Verify isolation and channel functionality annually with a multimeter
