BL20-GW-DNET Series Module (DeviceNet Gateway Module)

1. Basic Information

• Protocol Support: Compatible with the DeviceNet protocol (for industrial fieldbus communication).
• Protection Class: IP20 (suitable for cabinet-mounted installation, protected against solid objects larger than 12.5mm).
• Certification: cULus certified (meets safety and performance standards for North American and global markets).
• Ambient Temperature: Operating temperature range: 0°C - 55°C.

2. Hardware Features

• Address Setting: Node address is configured via a rotary DIP switch (for easy on-site parameter adjustment).
• Terminal Brackets: Equipped with 2 terminal brackets (model: BL20WEW35/2SW) for stable mounting.
• Terminal Block: Includes 1 terminal block (model: BL20ABPL) for wiring connections.
• Connector: Comes with 1 discrete wire connector (for flexible wire termination).
• Indicator Lights: Integrates power LED indicators, which display power supply voltage status, general alarms, and bus errors (for real-time status monitoring).

3. Electrical Parameters

• Power Supply: Powered by a BR power module, providing 5VDC with a current of 250mA.
• Communication Rate: Supports three selectable rates: 125kbps, 250kbps, and 500kbps (adapts to different fieldbus communication demands).

4. Functional Features

• I/O Module Support: Can connect up to 74 units, including various I/O types:
  • DI (Digital Input), DO (Digital Output)
  • AI (Analog Input), AO (Analog Output)
  • CT (Counter) units
• Address Assignment:
  • The DeviceNet node number and communication rate of BL20-GW-DNET are set via the front-panel DIP switch; the terminal resistor can also be configured via the DIP switch.
  • The input/output address "Words" of each Module Bus unit are determined by their slot positions, with the number of Words increasing from left to right.
• Status & Control Words:
  • The I/O Words scanned by BL20-GW-DNET include an additional 1 Word for input and 1 Word for output, serving as the status word and control word respectively. These two Words generally require no additional configuration.
