5. Connectors & Indicators

• Connectors: 3 × D-Sub or round connectors (depending on revision)

• LED Indicators:

  • PWR: Power OK (green)

  • IN0–IN14: Input status (green)

  • OUT0–OUT14: Output status (green)

  • SF: System Fault (red)

6. Core Functions

• Read external 24 VDC discrete signals (sensors, limit switches, safety doors, E-stop)

• Drive 24 VDC actuators (relays, solenoids, indicators)

• Provide safety interlock and emergency stop signal processing

• Filtering & surge suppression for EMI immunity

• Built-in self-diagnostics for circuit and channel faults

7. Application Scope

• Motoman XRC / MRC robot system I/O expansion

• Robot–PLC / robot–field device signal interface

• Production line safety monitoring and equipment interlocking

• Replacement / retrofit for older Motoman installations

8. Compatibility Note

• Not compatible with newer Yaskawa controllers (DX100, DX200, YRC1000)

• For those, use JANCD-XIO series boards instead.
