Model Meaning

• JANCD: Yaskawa CNC/Robot control board series

• 1004 / I004: 4‑channel high‑speed input interface

• C: 3rd revision (standard industrial grade, no conformal coating)

Specifications

Electrical

• Input Voltage: 5 V DC (logic level)

• Input Type: Sink/source selectable, 24‑channel digital input

• Isolation: Opto‑isolated, 500 V AC withstand

• Response Time: ≤ 1 μs (high‑speed sensor/encoder input)

• Current per Channel: 10 mA typical

Mechanical & Environmental

• Mounting: Standard rack‑mount (XRC controller slot)

• Protection: IP20 (dust protected)

• Operating Temp: 0 °C to +40 °C

• Humidity: 10%–80% RH (non‑condensing)

• Dimensions: 245 × 155 × 30 mm

• Weight: ~0.6 kg

Interface

• Connector: 1 × 50‑pin ribbon (J1)

• LEDs: 24 status LEDs (per‑channel input indication)

• Compatibility: XRC, NX100 (limited), YASNAC i80 (legacy)

Key Features

• High‑speed 5 V input for encoders, proximity sensors, and limit switches

• Direct plug‑in into XRC controller backplane; no external wiring needed

• Compact, fanless design for long‑term reliability

• Common replacement for worn JANCD-1004A/B boards

Applications

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

• Legacy YASNAC CNC (milling/turning machines with 5 V I/O)

• High‑speed automation requiring fast, noise‑immune 5 V input

• Retrofit projects replacing obsolete 1004A/B boards

Compatibility Note

• Not pin‑compatible with 1003‑series (1003B/C/D/E); different form factor & function

• Drop‑in upgrade for JANCD-1004A / 1004B
