Termination Unit Base ABB TU846 Industrial Control Backplane the module supports voltage andOverview The ABB TU846 is a passive termination unit (MTU) designed as the mechanical and electrical base for S800 I O modules. It provides secure wiring interfaces for ModuleBus communication, 24 V power distribution, and field signal connections in non redundant configurations. The TU846 includes mechanical keying to prevent incorrect module insertion, a rotary address switch for cluster configuration, and dedicated connectors to simplify system
