Product Description

The 1790D-T0B32 module is a DIN-rail-mounted temperature input module designed for the Allen-Bradley Flex I/O system, supporting 32 isolated analog input channels for temperature measurement via thermocouples or RTDs. It integrates seamlessly with other Flex I/O modules, enabling scalable industrial automation solutions. The module operates on a 24V DC power supply with a voltage range of 19.2–30V DC and functions reliably within a temperature range of -20°C to +60°C. Compatible with PROFIBUS-DP and Modbus protocols, it is widely used in process control, HVAC, and manufacturing industries. Key advantages include high channel density, easy configurability, and robust noise immunity, though it requires external signal conditioning for specialized sensors. Its compact design and DIN-rail mounting optimize space in control panels.
