3BHE029153R0101 UNS0119A-P,V101 | ABB Digital input submodule

Triple-Modular-Redundancy (TMR) ready – fits redundant CPU sets; provides isolated status acquisition for switches, proximity sensors and relay contacts.Converts 24 V DC field signals into back-plane logic levels; delivers channel health, SOE time-stamps and open-circuit detection to the CPU.Channels:16 sinking inputs (group of 16 isolated from back-plane)Rated Voltage: 24 V DC (18 … 30 V)Input Current:4 mA @ 24 V (current-limited)Thresholds: ON ≥ 15 V, OFF ≤ 5 V, 2 V hysteresisFiltering: 0 / 1 / 2 / 5 / 10 / 20 / 50 / 100 ms selectable per channel (default 2 ms)Minimum Pulse: 200 µs (filter = 0 ms)SOE Resolution:1 ms when used with redundant time-masterOpen-circuit Detection:Active current-source reports “open” when < 0.8 mAIsolation :500 V AC channel-to-back-plane, 250 V channel-to-channel
