Product Overview

The 1790D-T4R0 is a CompactBlock LDX DeviceNet base module from Allen-Bradley designed for input of up to four RTD or resistance temperature sensors. It operates as part of a distributed I/O architecture, communicating via DeviceNet to a central controller. Typical applications include temperature monitoring in light-industrial environments, process control panels, or machine-mounted sensor networks. 1790D-T4R0 handles analog RTD signals, enabling real-time data transfer when integrated into CompactBlock LDX systems.
