Entry-Level Modbus Gateway
EKI-1211

EKI-1211 Modbus gateway is an entry-level bi-directional gateway for integrating new and existing Modbus/RTU and Modbus/ASCII serial devices to newer TCP/IP networked-based devices. Its compact size means it's suitable for limited space applications, and bring remote management and data accessibility to devices that cannot otherwise connect to a network.

Feature Highlights

Seamless Communication Between Modbus and Ethernet Devices

  • Equipped with 1 x serial port and 1 x Ethernet port.
  • Integrates Modbus TCP and Modbus RTU/ASCII networks
  • Leverages common RS-232/422/485 standard interfaces

Industrial Grade Hardware Design with UL Safety Certification

  • Adheres to EMC and UL certification standards
  • Encased within an industrial-grade, ruggedized metal housing
  • Supports broad operating temperatures of -10 ~ 60 °C (14 ~ 140 °F)
  • Excellent solution for applications within harsh, limited-space environments

Easy-to-use Design

  • Easy to deploy and maintain. Upgrades equipment for better data accessibility without wasting original investments.
  • Monitors and diagnoses serial port status for easy troubleshooting and reduced maintenance.
  • Provides a configuration duplicates function in WebGUI for reducing deployment times.
