NE810 is an Industrial switch made for harsh environments. Due to

our multi-rate SFP solution, the switch can be used in either 100

Mbit or Gigabit networks. Our unique FRNT (Fast Recovery of

Network Topology) technology is the fastest protocol on the

market to re-configure a network in case of any link or hardware

failure. That is why NE810 is also used in safety-critical applications

such as tunnels, traffic signal control, and railway systems.

Installations in harsh environments and places with heavy electrical

interference require the use of reliable media. NE810 provides a

number of solutions using fiber optic transceivers. Multi- or singlemode

transceivers can be used to build point-to-point or

redundant ring networks with ranges up to 120 km between each switch.

a single fiber can be used in applications where the number of fiber

cores is limited.

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.

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.

Modular structure of the AC 800PEC control system

The modular structure of the system means that it can be adapted to any size of application,

from the largest industrial equipment and propulsion systems to compact products where space and cost

are critical.

All over the world, thousands of processors have proved their worth in a wide range of extremely

demanding applications.

Powerful hardware for efficient high-speed processing

The AC 800PEC combines the floating-point performance of a CPU with the flexibility and high-speed

capability of an FPGA.

The system is divided into three performance levels covering different cycle times.

Control tasks are assigned depending on their speed requirements:

– Very fast tasks, down to 25 nanoseconds (nanoseconds for FPGA tasks)

– Fast tasks down to 100 μs (microseconds for Matlab/Simulink tasks)

– Slow tasks down to 1 ms (milliseconds for control tasks)

The hardware architecture of the AC 800PEC is complemented by a three-level software architecture.

To support short processing cycles, the AC 800PEC offers a fast I/O system.

Depending on the speed of the I/O connections, data throughput times can be less than 100 μs,

 including the time required to read, process, write and transmit signals.

Implementing the AC 800PEC software at three performance levels provides excellent control and

communication capabilities.

The following software packages have been developed to support each specific high power rectifier

application.

Built for power control in the process industry

ABB has global expertise and know-how in the field of process control for industrial, marine and other

applications.

As a result, the AC 800PEC is a key controller for ABB industrial applications as well as third-party

products and systems.

Preventive maintenance program

ABB has designed its maintenance schedule for all contactor

families, based on its technical knowledge of the products and

on its experience in the field.

The preventive maintenance program has the following main targets:

• Check the preservation and the efficiency status of the apparatus

• Anticipate the trend of deterioration of the contactors, signalling

the need for replacement of excessively worn out components,

where available, or suggest alternative solutions for bringing them up to date

• Increase the life cycle of the installation, proposing proactive

maintenance and replacing obsolete components.

Provided services

Considering the importance of the maintenance activity and

the required technical know-how, ABB guarantees professional

competence. Interventions are performed by ABB recommended

skilled technicians. After the inspection activities, ABB technicians

give all the indications related to the future maintenance needs and

any possible corrective actions, while releasing the final report.
