ABB TU810V1 3BSE013230R1 Terminal Unit Base
TU810V1 3BSE013230R1 is a standard terminal base unit for ABB S800 I/O modules, manufactured in Sweden and compatible with AC800M, AC800F controllers and 800xA DCS systems. It serves as the wiring carrier and mechanical support for S800 I/O modules, providing field signal wiring terminals, backplane bus connection and power distribution for mounted DI/DO/AI/AO modules.

This base adopts spring-cage quick wiring terminals, supports hot swap of I/O modules without cutting off field external wiring. It features built-in bus communication contacts and auxiliary power distribution circuits, widely used in chemical, power, water treatment industrial control cabinets for signal wiring expansion and damaged base replacement.
