Product Identification
Model: 6DS1144-8AA
Manufacturer: Siemens
Type/Function: 8-channel I/O-bus
What it is?
The 6DS1144-8AA is an 8-channel I/O-bus comparator & switch-over module that continuously watches two parallel buses,
cuts over in < 1 ms and keeps your AS 235 H extension unit running even when one side develops a fault.
Key Technical Specifications
Part no：6DS1144-8AA
Function：I/O bus comparator + automatic switch-over
Channels：8 digital I/O lines (bus A vs. B)
Switch-over time：< 1 ms, bumpless
Bus isolation：1 kV A-to-B
Power draw：100 mA @ 5 V (from rack)
Accuracy：±0.05 % reference comparison
MTBF： @ 40 °C 310 000 h (SN 29500)
Application Scenarios
l Power-gen turbine hall: single module prevents bus-fault trips, saves 50 MW restart
l Cold-store distribution: –25 °C panel air, 24/7 operation since 1998, zero drift
l Offshore water-flood: keeps redundant I/O islands alive without extra CPUs
