Select I/O is a Ethernet based single channel I/O solution for ABB Ability™ System 800xA that offers full redundancy down to the Signal Conditioning Module.
Each signal coming from the field is conditioned individually with the Signal Conditioning Module (SCM) for both process and safety applications.
Select I/O was designed with parallel project execution in mind.
Termination units can be installed on site long before the electronics are installed.
Site engineering can be done completely independently from application programming.
Features
Individual Signal Conditioning Modules (CSMs) available for process, safety (SIL3)
and intrinsically safe applications
