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.

The DIS801 is a Digital Input 24 V Signal Conditioning Module

supporting 2/3/4-wire devices with Sequence of Events (SOE).
