Sixnet ST-AI-20M-08 Analog Input Module

The ST-AI-20M-08 is an eight-channel analog-input module in Sixnet’s SixTRAK I/O family, designed to bring eight 4-20 mA process signals into a SIXNET controller or RTU. Typically ordered as the ST-AI-20M-08F with a wiring base, this module accepts eight current inputs in the standard 4-20 mA range and ships in a compact form factor that fits a Sixtrak I/O chassis; the base measurements are 4.5 in wide by 1.5 in high by 4.0 in deep (11.4 cm x 3.8 cm x 10.2 cm), and the unit weighs about 0.1 kg, enabling easy mounting in control panels or racks. As part of the Sixnet ecosystem (now Red Lion), the ST-AI-20M-08 is intended to be connected to a SixNET controller or Open DCS/RTU solution, such as the SixTRAK IPm series or related EtherTRAK gateways, to provide reliable, field-wiring-ready measurement of plant signals and centralized logging and control. This configuration is commonly used to monitor sensor networks in process automation, where multiple 4-20 mA analog inputs must be collected by a single controller for real-time trending, alarming, and SCADA integration.
