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.

A Modulebus Terminator is required for termination of the Modulebus at the end of each cluster. If Compact Modulebus Extensions are used between groups of I/O units, the Modulebus Terminator has to be placed at the end of the last group. The Module Terminator is connected at the bottom of the last I/O MTU. One Modulebus Terminator is needed per cluster.

Features and benefits

• Terminates the Modulebus.

• DIN rail mounted. Locking device locks it to the DIN rail.

• Locking device that locks the Modulebus Terminator to the MTU for Select I/O.

• Can be used in hazardous area.
