Main Features

1. Basic 64‑point I/O: Compact, cost‑effective digital I/O for standard machines.

2. Sink/source selectable: Works with both PNP and NPN sensors/actuators.

3. Noise immunity: Opto‑isolation and surge protection for industrial environments.

4. Diagnostic LEDs: Quick status check for power, run, alarm, and I/O activity.

5. Legacy drop‑in: Direct replacement for original 10O1B/1001B in YASNAC and Motoman systems.

Applications

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

• Motoman XRC robots (handling, assembly, welding)

• General automation with medium I/O density

• Replacement for failed JANCD-10O1B/1001B boards

Compatibility

• Not interchangeable with 1003 (servo I/O), 1004 (digital input), 1006 (encoder I/O), 1020/1021 (high‑density I/O).

• Direct swap within 10O1B/1001B/IO01B.
