136188-02 | BENTLY NEVADA | Ethernet/RS485 Modbus I/O Module

BENTLY NEVADA 136188-02 3500/92 Ethernet/RS485 Modbus I/O Module

 Specifications:

Inputs

• Power Consumption:
  • 5.0 watts typical with Modbus RS232/RS422 I/O Module
  • 5.6 watts typical with Modbus RS485 I/O Module
• Data Types:
  • Collects data from other modules in the rack, such as current proportional values with time stamp, module statuses, and current alarm statuses, via a high-speed internal network. Exact data types returned depend on module type and channel configuration.
• Update Time:
  • The data collection rate depends on rack configuration but will not exceed 1 second for all modules in the 3500 rack.

Outputs

• Front Panel LEDs:
  • OK LED: Indicates when the 3500/92 is operating properly.
  • TX/RX LED: Indicates when the 3500/92 is communicating with other modules in the 3500 rack.

Protocols

• BNC Host Protocol:
  • Communication with 3500 Configuration Software and 3500 Data Acquisition and Display Software over Ethernet TCP/IP.
• Modbus®:
  • Based on AEG Modicon PI-MBUS300 Reference Manual. Uses Remote Terminal Unit (RTU) transmission mode. Modbus is a registered trademark of Modicon, Inc.
• Ethernet Communication Link:
  • Ethernet, 10Mbps, and conforms to IEEE802.3.
• Protocol:
  • Ethernet TCP/IP frame and Modbus/TCP.
• Connection:
  • RJ-45 (telephone jack style) for 10BASE-T Ethernet cabling.

Environmental Limits

• Main Module:
  • Operating Temperature: -30°C to +65°C (-22°F to +150°F).
  • Storage Temperature: -40°C to +85°C (-40°F to +185°F).
  • Humidity: 95%, non-condensing.
• I/O Module:
  • Operating Temperature: 0°C to +65°C (+32°F to +150°F).
  • Storage Temperature: -40°C to +85°C (-40°F to +185°F).

Dimensions

• Height x Width x Depth: 241 mm x 24.4 mm x 99.1 mm (9.50 in x 0.96 in x 3.90 in).
• Weight: 0.44 kg (0.96 lb.).

I/O Modules

• 1 full-height rear slot.

Serial Cabling (RS422/RS485)

• RS422 Cables can be used for rack-to-rack connections when using Modbus RS485 I/O Modules. The final rack-to-host connection is application-specific and may require a custom cable.
