3. Functional Description

3.1 Core Functions

1. Isolated Relay Outputs

   • Provides 8 channels of isolated NO relay contacts.

   • Switches high-power external loads separate from robot control circuits.

2. Load Switching Control

   • Controls welding peripherals: gas valves, wire feeders, coolant pumps.

   • Drives external contactors, alarms, and process interlocks.

3. Status Indication

   • On-board LEDs for each channel: ON = relay energized.

   • Enables quick visual diagnostics of output status.

4. Bus Communication

   • Communicates with XRC main boards (e.g., JANCD-XEW01/02) via internal bus.

   • Receives on/off commands from robot program or teach pendant.

4. Compatibility & Installation

4.1 Compatibility

• Exclusive Compatibility: Motoman XRC series robot controllers (all applications).

• Incompatible With: NX100, NXC100, DX series, and Yasnac CNC systems.

4.2 Installation Steps

1. Power Off: Disconnect controller power; wait ≥5 minutes for capacitor discharge.

2. ESD Protection: Use ESD wristband to prevent static damage.

3. Slot Insertion: Insert into dedicated I/O slot on XRC backplane.

4. Connector Wiring:

   • Wire common (COM) and normally open (NO) contacts to external loads.

   • Use appropriate gauge wire for 10 A / 250 VAC ratings.

5. Power On: Restore power; verify board recognition via teach pendant.

5. Maintenance & Safety

5.1 Maintenance Guidelines

• Periodic Inspection: Every 3 months, check connectors and wiring for wear or loose terminals.

• Cleaning: Use dry, lint-free cloth; avoid liquid cleaners.

• Relay Life: Rated for ~100,000 operations (resistive load); replace if contacts burn or stick.

5.2 Safety Precautions

• High Voltage Warning: Relay contacts may carry 250 VAC; de-energize external circuits before servicing.

• Qualified Personnel: Installation/maintenance only by certified technicians.

• Static Sensitivity: Always use ESD protection when handling the board.
