Product details

8-channel analog input for S7-300

The 6AG1331-7TF01-4AB0: Input resistance is 240 Ω across the rated range, with reverse polarity protection on the signal side. Integration time is parameterizable: 20 ms at 50 Hz, 16.6 ms at 60 Hz, or 100 ms at 100 Hz.

Diagnostics and compliance

Diagnostic functions include a group error SF (red) LED, readable diagnostic information, limit value alarm, and diagnostic alarm. Isolation is tested at 500 V between the channel group and the backplane bus; channels within the group are not isolated from each other. The module carries UL approval (File E239877), FM approval (CofC 3028431), CE mark, KC approval, EAC, and RCM.
