1. Overview

• Type: Digital input/output PCB (legacy compact model)

• Controller: XRC1000, XRC2001 (XRC series only)

• Function: 8‑in / 8‑out discrete I/O for basic sensor/actuator interfacing

• Part number: JANCD-XIO02; older revision JANCD-XIO02/B

• Status: Obsolete; replaced by XIO01/XIO01B

2. Specifications

• Power: 24 VDC ±10%, ~8 W

• Inputs: 8 channels, non‑isolated, 0–30 VDC, sink/source selectable

• Outputs: 8 channels, transistor (NPN/PNP selectable), 24 VDC, 0.5 A/ch

• Comm: No onboard serial (no RS‑485/Modbus)

• Operating temp: 0 °C ~ +40 °C (narrower than XIO01)

• Storage temp: ‑40 °C ~ +85 °C

• Humidity: ≤80% RH (non‑condensing)

• Dimensions: 100 × 45 × 25 mm; weight ~0.15 kg

3. Connector Pinout

• CN1: 24 VDC, GND

• CN2: IN0–IN7 (8 inputs)

• CN3: OUT0–OUT7 (8 outputs)

• CN4: Internal bus to CPU (JANCD‑XCP01)

• No RS‑485 port (unlike XIO01)

4. Key Differences (XIO02 vs. XIO01/XIO01B)

• I/O count: XIO02 8‑in/8‑out; XIO01/XIO01B 16‑in/16‑out

• Communication: XIO02 no serial; XIO01 RS‑485 Modbus RTU

• Temperature range: XIO02 0~+40 °C; XIO01 ‑20~+60 °C; XIO01B ‑10~+55 °C

• Reliability: XIO01/B have improved EMC and component derating

• Compatibility: XIO02 is pin‑compatible with XIO01/B but offers fewer features

5. LED Indicators

• PWR (green): 24 VDC OK

• RUN (green): Board active, CPU communication normal

• IN0–IN7 (yellow): Input status (ON = lit)

• OUT0–OUT7 (yellow): Output status (ON = lit)

• ALM (red): Overload, short circuit, or bus error

6. Compatibility & Replacement

• Fits: XRC1000, XRC2001 (XRC series only)

• Replaced by: JANCD-XIO01B (direct swap, more I/O, Modbus, wider temp)

• Not for: DX200 (uses JANCD‑AIO01‑E)

7. Installation Notes

• Power off controller; wait ≥5 min for discharge

• Use anti‑static wristband

• Back up CMOS/job data before replacement
