MTL 8709-CA-08 Modbus TCP/IP to HART Gateway

Overview

The MTL 8709-CA-08 is a compact, high-performance Modbus TCP/IP to HART gateway. It connects Modbus TCP/IP controllers, such as PLCs, DCSs, and HMIs, to HART field devices. The device enables communication with instruments like pressure transmitters, flow meters, and temperature sensors. Users can configure it easily via a web server interface. It operates reliably in harsh industrial environments and mounts conveniently on DIN rails or panels.
