Selection Notes

The SR3B261FU runs directly from 100–240 V AC and offers the same 16 discrete input / 10 relay output count as the DC-supplied SR3B261BD, so it is the choice when the panel has no 24 V DC rail already available; the AC input circuit debounces in 50–255 ms versus millisecond-range response on the DC unit. Two of its ten relay outputs are current-limited to 5 A while the other eight carry 8 A — route higher-current loads to the 8 A-rated points.
