Select I/O is an Ethernet networked, single channel granular I/O system for the ABB Ability™ System 800xA automation platform. Select I/O helps decouple project tasks, minimizes the impact of late changes and supports standardization of I/O cabinetry ensuring automation projects are delivered on-time and under budget. A Signal Conditioning Module (SCM) performs the necessary signal conditioning and powering of the connected field device for one I/O channel.

TUS810 is the MTU for the I/O unit. Together with a GIO and up to 16 SCMs with FTBs, it implements an I/O unit.
The local I/O bus (Modulebus) distributes communication, system power and field power to the I/O modules (GIO and SCM). The power is distributed in the back plane. For high voltage and high current channels, the field power has to be supplied from the PTB. There is coding on the FTB designed for the SCM so that, if an SCM is replaced, only the same type of SCM can be inserted. This coding is self-learning, i.e. it is set the first time the SCM is inserted. To insert another type, the coding has to be reset manually. The MTU has a coding for the GIO, so that it can only be replaced with the same type of GIO. TUS810 cannot be replaced with power applied.

The Select I/O Module Termination Unit TUS810K01 includes 1ps TUS810, 16ps FTB810 Field Terminal Blocks, 2ps PTB810 Power Injection Terminal Blocks and 1ps TUC810 Terminal Cover. Mounting on vertical DIN-rail.
