8810 Remote Terminal Unit

Next Generation Communications Device

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.
