Long-term use

Analog devices (inputs, outputs) are subject to constant environmental influences during operation
(temperature, temperature change, shock/vibration, irradiation, etc.) This can affect the function, in particular
the analog accuracy (also: measurement or output uncertainty).
As industrial products, Beckhoff analog devices are designed for 24h/7d continuous operation.
The devices show that they generally comply with the accuracy specification, even in long-term use.
However, as is usual for technical devices, an unlimited functional assurance (also applies to accuracy)
cannot be given.
Beckhoff recommends checking the usability in relation to the application target within the scope of normal
system maintenance, e.g. every 12-24 months.
