I. Product Introduction

1. Usage

It is specifically designed for the control cabinet of the old model Motoman XRC robot, serving as an advanced I/O expansion board.

It integrates safety circuit monitoring + general I/O + external device interface, mainly used in welding, handling, spraying and other process stations.

2. Core Functions

✅ Safety Interlock Processing: Hard logic monitoring of emergency stop, safety door, limit signal

✅ General I/O Expansion: Supplementing the insufficient standard I/O board slots

✅ Peripheral Special Interface: Compatible with welding machines, manipulators, PLC linkage signals

✅ Status Monitoring: On-board LED, real-time display of I/O and safety circuit status

✅ System Bus Communication: High-speed data interaction with XRC main control board

3. Electrical Specifications

Model: JANCD-I007-1 (I007 is omitted - 1)

Input: 32 DC24V (including 8 safety-specific inputs)

Output: 24 DC24V transistors, single point 0.5A

Interfaces: CN1 (50-pin), CN2 (40-pin), CN3 (20-pin)

Power Supply: Backplane DC5V + external DC24V (2A)

Size: Approximately 310×215 mm (standard JANCD large board)

Temperature: 0℃～40℃, no condensation

Humidity: ≤80%, no condensation

II. User Manual (Core Points)

1. Installation (XRC Control Cabinet)

Slot: XRC dedicated I/O slot (ST#03/ST#04)

Fixation: 4 M3 screws, torque 0.8～1.0 N·m

Compatibility: Only XRC models, not applicable to ERC / new DX series cabinets

2. Wiring (CN1/CN2/CN3)

CN1 (50-pin): General input 24 points + output 16 points

CN2 (40-pin): Safety input 8 points + dedicated output 8 points

CN3 (20-pin): Power + communication + status signal

Safety Input: NPN type, low level valid, connect emergency stop / safety door

Output Wiring: Positive pole of load connected to 24V+, negative pole connected to OUTx, common terminal COM connected to 0V

⚠️ Safety circuit must not be paralleled, must be independently wired to ensure reliable shutdown

3. I/O Address (XRC System)

General Input: IN100～IN131

General Output: OUT100～OUT123

Safety Signal: Fixed address of the system, cannot be modified

Check: Teach Pendant → Input/Output → Extended I/O

4. Fault Troubleshooting

Safety Error: Check CN2 wiring, emergency stop button, safety door contacts

I/O No Response: Check DC24V power supply, CN3 communication line, board card pins
