Real-time properties are implemented in the switch in order to

achieve determinism for real-time critical applications. NE810

supports QoS (Quality of Service) with four priority queues and

strict priority scheduling as well as HoL (Head of Line Blocking

Prevention). All to assure that the data network is deterministic.

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.rnA Signal Conditioning Module (SCM) performs the

necessary signal conditioning and powering of the connected field

device for one I/O channel.

This product family is in the scope of European Union directive 2012/19/EU on Waste Electri

cal and Electronic Equipment (WEEE). The product family must be disposed according to the

legislation of the country. This the end-of-life instructions is intended for use by customers

and recycling companies which outline the responsible recycling or disposal method of the

ABB product.

Selective main circuit-breakers of the S 750 series are SMCBs based on DIN VDE 0641-21 with

voltage-independent operating principle. This means that they do not rely on a control circuit

to make or break contact (SHU) and are therefore particularly suitable for use in energy distri

bution systems with maximum availability requirements. They offer total selectivity to down

stream MCBs and outstanding selectivity to upstream protective devices due to unique cur

rent limiting selectivity.
