8810 Remote Terminal Unit

8810 Remote Terminal Unit

The 8810 Remote Terminal Unit (RTU) is a modular, Ethernet enabled, communications device. Its powerful industrial chassis is ideal for integration with tank gauges and other field devices used in inventory management applications. With support for up to six interface modules, it is extremely flexible in handling data exchange across multiple communication protocols.

Next Generation Communications Device

Android Display Coming

With the CPU module serving as the base functionality for the 8810 RTU, all logic and protocols are handled seamlessly, meaning there is only one firmware application for the entire unit.

The standard, built-in OPC Unified Architecture (OPC UA) server communicates natively over standard internet protocols. This allows human machine interface (HMI) applications to read data from the 8810 RTU. It is also compatible with a wide range of systems, including legacy Varec systems, using RS-232 and RS-485 standards.

  • Ethernet enabled, provides high-speed communications in near real time
  • Industry standard OPC UA
  • 800 MHz, 4-core CPU
  • Multi-threaded task handling
  • Modbus for host or field integration via Serial RTU, Modbus TCP, or Modbus
    over TCP
  • Channels can be configured as Modbus Slave or Master
  • Supports up to 400 tanks
  • Supports up to 24 communication channels
  • Digital input/output for alarms, monitoring and control
