System 800xA offers flexible and modular I/O solutions through fieldbus technologies and hardwired I/O systems like S800 and S900. The system is now enhanced with Select I/O that allows to condition each signal coming from the field individually. Select I/O is Ethernet connected and consist of single channel granular Signal Conditioning Modules (SCM).

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.
