The sum data amplifier adds up or subtracts up to 4 singly rateable input signals and converts these to a sum proportional or difference proportional output signal. As input signals, currents up to 20 mA or voltages up to 10 V (also bipolar) are possible. The inputs are galvanic separated from the auxiliary voltage and the outputs. The two analogue outputs current (max. 20mA) and voltage (max. 10V) can be utilised simultaneously. The device can be configured with the optional configuration software AD-Studio via the interface AD-PC. However, this can also be carried out at the works according to customer data.



Analogue summing/subtraction of single measurable variables such as through flows, outputs or quantities.
