Model Definition

• JANCD: Yaskawa CNC/robot control board series

• 1021: 10-series, high-density I/O board (upgrade of 1020)

• Rev A01: Common hardware revision; DF8202440: Yaskawa internal part number

Key Specifications

Electrical

• Power Supply: 24 V DC ±10%

• I/O Points: 112 inputs / 68 outputs (24 V DC, sink/source selectable)

• Isolation: Opto-isolated, 500 V AC dielectric strength

• Response Time: ≤2 μs

• Connectors: 5×50-pin ribbon cables (J1–J5)

• LEDs: 20 status indicators (power, run, alarm, I/O status)

Mechanical & Environmental

• Mounting: Standard rack slot (i80/i90 CNC, XRC robot backplane)

• Dimensions: 245 × 155 × 30 mm

• Weight: Approx. 1.4 kg

Main Features

1. High-Density I/O: 180 I/O points total (112IN/68OUT), 40% higher than JANCD-1020, ideal for complex machines.

2. Enhanced Compatibility: Directly compatible with YASNAC i80/i90 CNC and Motoman XRC robot controllers.

3. Noise Immunity: Opto-isolation and differential signaling ensure reliability in harsh industrial environments.

4. Diagnostic LEDs: Real-time status monitoring for quick troubleshooting.

5. Legacy Replacement: Drop-in upgrade for JANCD-1020; no wiring changes required.

Applications

• YASNAC i80/i90 CNC (milling, turning, machining centers)

• Motoman XRC robot controllers (welding, material handling, assembly)

• Legacy automation requiring high-density discrete I/O

• Replacement/retrofit for failed JANCD-1021 or JANCD-1020 boards

Compatibility Notes

• Not interchangeable with JANCD-1003 (servo I/O), 1004 (digital input), or 1006 (encoder I/O) series.

• Backward compatible with JANCD-1020 (direct swap, no wiring changes).
