4.2.3.2 Connection examples for analog measuring inputs with the module
6DR2800-8J
In current inputs the input load resistance is between AI+ and AI--.
If the signal is still required during service work in which the terminal is disconnected, the input
load resistance must be connected to the terminal between AI+ and AI--. The internal 49.9
Ω
resistance must then be disconnected in 6DR2800-8J by appropriate rewiring.
