Temperature measurements represent the numerically largest group of analog interfaces in industrial automation. All the more reason why technical perfection and cost-effectiveness are important requirements here. The AIO112 module types cover both of these requirements in an exemplary manner. Up to 12 Pt100/Pt1000 sensors can be cost-effectively connected to a single module using a 2-wire connection technology.

The temperature is recorded with 16‑bit resolution and, thanks to special measuring electronics, with very high sampling rates. Widely adjustable filter chains, precisely tuned to the signal path, ensure a configurable balance between interference suppression and measurement dynamics. A hardware-accelerated high-speed interpolation that can be activated as required provides continuous measurement signals independent of the filter settings and even with very short bus cycles. Alternatively, each individual channel can also be operated as a 14 bit current output (4 mA to 20 mA, 0 mA to 20 mA).
