S800 I/O REDUNDANT TERMINATION
ABB TU848 is a passive S800 I/O module termination unit for redundant TB840 or TB840A Optical ModuleBus Modem configurations with redundant I/O. The unit provides separate 24 V DC power connections for the two modems, dual electrical ModuleBus paths, two modem positions and a rotary switch for cluster addresses from 1 to 7. Mechanical keying helps prevent an incorrect module type from being inserted, while the DIN-rail latch provides locking and grounding. Verify article number 3BSE042558R1, power feeds, modem pairing, I/O redundancy and cluster address before replacement.
