I. Product Introduction

1. Function

Used for the control cabinet of Motoman XRC/ERC robots to achieve digital signal interaction between the robot and external devices (PLC, sensors, fixtures, safety doors, emergency stop).

40 DC24V inputs + 40 DC24V outputs are provided. General I/O can be freely assigned addresses.

2. Core Functions

✅ Collect emergency stop, safety door, limit switch, etc. safety interlock signals

✅ Control fixtures, solenoid valves, conveyor belts, etc. actuators

✅ Connect and isolate with upper-level PLC / machine I/O signals

✅ Built-in LED, real-time display of each I/O status for easy diagnosis

✅ Support ladder diagram programming, custom logic

3. Electrical Specifications

Input: 40 points, DC24V, NPN (low level valid)

Output: 40 points, transistors, DC24V, maximum 0.5A / point

Interface: CN1～CN3 (3 50-pin flat cable sockets)

Power supply: Backplane DC5V + external DC24V (recommended independent 24V power supply)

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

Weight: Approximately 0.7～0.8 kg

Operating temperature: 0℃～40℃, no condensation

Relative humidity: ≤80%, no condensation

II. User Manual (Key Points)

1. Installation (XRC/ERC Control Cabinet)

Slot: Standard I/O slot (e.g., ST#02)

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

Connection: Gold fingers plug into the control cabinet base plate; CN1～CN3 connect external I/O cables

2. Wiring (CN1～CN3, each port 50 pins)

Input (IN0～IN39):

Common terminal: COM1～COM3 (24V+)

Signal terminal: INx connects to the negative pole of the external switch/sensor (NPN)

Output (OUT0～OUT39):

Common terminal: COM4～COM6 (0V)

Signal terminal: OUTx connects to the negative pole of the load, positive pole connects to 24V+

⚠️ Output must not overload: single path ≤0.5A, entire board ≤1.5A

3. I/O Address Allocation (XRC/ERC System)

General input: IN0～IN39 → Address 00010～00047

General output: OUT0～OUT39 → Address 00050～00087

View / Force: Teaching device → Main menu → Input / Output → General I/O

4. Fault Diagnosis

Input does not light up: Check 24V power supply, COM terminal whether connected to 24V+, sensor polarity

Output does not actuate: Check load wiring, COM terminal whether connected to 0V, program / ladder diagram logic

Communication error: Check board card tightness, cable connection, firmware version matching
