ABB S 751 DR-E20 2CDH781001R0202 S 751 DR

The unit is designed for use in industrial applications with dual 10 to

57 VDC power input. The unique “tri-galvanic” isolation provides

isolation between al ports, power supply and between each chassis

screen avoiding ground loop currents. The IP21 rating ensures that

the unit can be instaled in locations where condensed water may

occur. Only industrial grade components are used which gives the

units an MTBF of 1.182.000 hours and ensures a long service life. A

wide operating temperature range of –40 to +70 °C (–40 to +158 °F)

can be achieved with no moving parts.

Features and benefits

• Pre-configured for use with System 800xA

• NE810 supports redundant power connection

• Enhanced monitoring using PNSM

• Industrial Ethernet 10-port switch

• Long life duration

• Fully supported by ABB

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.
