Product Description:

The 7CI410.70-1 analog input module is built by B&R Automation and belongs to the System 2003 Controllers series. Designed as an expansion element for modular PLC backplanes, the unit captures temperature data from industrial processes and forwards digitized values to the central CPU. By providing two isolated channels dedicated to temperature sensing, the module allows thermal feedback to be integrated into closed-loop control routines without occupying high-speed digital slots. In furnace supervision, packaging heat-seal control, or environmental chambers, it serves as the point of entry for low-voltage sensor signals that the controller later scales and evaluates.

This analog input module measures 60 mm in height, 20 mm in width, and 85 mm in length, so it occupies a single slot next to neighboring control cards while keeping cabinet depth short in compact panels. With a mass of only 0.10 kg, it adds minimal load to DIN-rail assemblies and remains easy to handle during installation. The module locks onto the backplane as a screw-in module, which helps maintain secure retention after the two captive screws are tightened. Internal bus connectors route power and data, leaving the front panel free for field terminals and diagnostic LEDs.

Each of the two temperature channels is engineered for non-contact acquisition, allowing sensors such as infrared pyrometers to be wired without thermowells or immersion probes. The circuitry accepts exactly 2 inputs, and the application program can sample them individually or average them for redundancy. Signal conditioning supports a thermal span from 0 °C up to +300 °C, so the same card can supervise ambient conditions as well as moderate-temperature ovens. These limits are maintained through precision resistive dividers and calibrated ADC reference points, giving the controller predictable resolution across the full operating window.
