The analog input module AIM4 has four measuring inputs, which can be used either as a voltage input, with a measuring range of 0 to +10V, or as a current input, with a measuring range of 0(4) to +20mA.

The channels are galvanically isolated and can therefore be operated at different potentials. Earth loops are avoided. The power supply is provided via the system bus. Three diagnostic LEDs indicate the correct operating voltage as well as the reception and transmission of bus data. The module is suitable for mounting on 35 mm DIN rails and is supplied with four 3-pole plug-in terminals. The software integration of the module is carried out via the dinotecNET+ system.
