Sixtrak ST-AI-INS-08UB Analog Input Module

The ST-AI-INS-08UB is an eight-channel instrumentation analog input module from the SixTRAK family, designed to feed a SIXNET controller or RTU with a variety of field-signal formats. It provides eight isolated input channels with two screw terminals per input for secure field wiring, and accepts thermocouples, millivolts, and other instrumentation signals. For 4-20 mA loops, per-channel enable jumpers configure the channel for current input, and autopolarity helps maintain correct readings even if loop polarity is reversed. Thermocouple burnout detection (upscale or downscale) can be enabled for safer process monitoring, while the analog inputs are isolated from one another to minimize cross-talk and ground loops. As part of the SixTRAK I/O family, the ST-AI-INS-08UB is designed to be connected to a SIXNET/SixTRAK controller or RTU (for example IPm/Open DCS controllers or SixTRAK I/O gateways), and is documented as an Instrumentation Analog Input Module (8 AI) or Analog Input Universal Base Module, reflecting its role in acquiring precise low-level signals for temperature, mV, and related instrumentation applications.
