NOTICE
Factors affecting maximum cable length

Be aware that the cable resistance and the influence of EMC as well as the hum is increasing with the cable length and has an impact on the accuracy of the analogue value.

If the maximum cable length can be reached in an application depends on factors like selection of cable type, -dimension, shielding, wiring, distance to high power devices, the requirements regarding measurement and control accuracy etc. and is in the responsibility of the customer.
