Key features include:

• A wide range of I/O interfaces with optionally

integrated intrinsic safety (Ex i) design and

transmitter power supply. Features such as

time stamping with a 1 ms resolution,

monitoring, filtering and HART communication

are implemented directly in the I/O modules

• PROFIBUS interfaces provide connections to

ABB’s S800 and S900 remote I/O stations in

Ex and non-Ex versions, as well as other PROFIBUS devices

• IEC 61850 interface to intelligent electronic

devices (IEDs) for the integration of electrical subsystems

• Modbus RTU and TCP interfaces provide

connections to 3rd party devices

• The MR Series control network uses a

redundant, high-speed serial communication

network with inherent capability for remote

communication. The network is easy to handle,

without requiring routing configuration

• Flexible mounting alternatives such as cabinet,

DIN rail or 19” rack mounting. All three can be

combined in one project. This allows optimal

adaptation to all plant structures and supports

flexible upgrades of existing installations

• An unrivaled high packing density in the

system cabinets saves installation space

• Controller time synchronization based on

a time precision of 0.5 msec

• Sequence of events (SOE) time stamping

with a resolution of 1 ms is implemented

in the controller and local I/O module level
