Temperature measurements represent the numerically

largest group of analog interfaces in industrial automa

tion. All the more reason why technical perfection and

cost-effectiveness are important requirements here. The

AIO116 module types cover both of these requirements in

an exemplary manner. Up to 16 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 bal

ance 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 indi

vidual channel can also be operated as a 14 bit current

output (4 mA to 20 mA, 0 mA to 20 mA).
