ABB has introduced a new motor protection relay, the M102. The M102 relay is part of the INSUM range of motor protection products and is specifically targeted to meet some of the unique requirements of the mining industry, water treatment plants, wastewater applications, general process industry, cement industry and food processing industry.
The M102 is easy to operate, connects easily to any control system and is fully type tested to Australian standards. It uses standard communication cables, can be programmed both remotely and via the control system and is also suitable as part of a retrofit solution.
There are two options of protocols used for interfacing with the upper level control system - the Modbus RTU and Profibus DP. The redundant ports provided in the M102 relay with Modbus RTU protocol makes it possible to build up the stable redundancy communication network.
In addition, the M102 is able to continuously collect and relay data without interrupting processes, providing timely and accurate protection by giving fault alarm and protection trip to safeguard motors and ensure a smooth production process.
ABB has a fully trained team in Australia to provide local service to remote mining sites.
Our experience is at both field level as well as our local installed base covering both the mining and water treatment industries.
Motor protection relays are designed to protect electrical equipment against thermal overload, motor stall, phase failure, phase imbalance, no load, overload, earth fault and motor overheat, with a focus on providing comprehensive and dedicated protection for motors.
Thermal overload protection keeps track of and calculates the thermal capacity of the motor in operation. This protects the motor against overheating, which can shorten the service life of the motor or damage it. Additionally, the thermal memory function of the thermal overload protection is particularly important in cases where frequent starting is required. The M102 unit simulates the thermal conditions in all operating states of the motor which maximises its use on the premise of safe operation.

M102 relay programming software
The M102 relay programming software is available in two versions : Profibus and Modbus.
Including a handy help- function, the software package can be ordered via email from
regina.roos@au.abb.com. Ensure that you include in your email the information for which project and bus communication it is required.
Smart relays introduction seminars
ABB offers lunchtime seminars at customer sites (duration 90 minutes ).
The sessions will familiarize you with the basics of the products and help you to understand the application set-ups.
During the presentation, the features and values of the system are outlined as well as demonstrations that will create a solid understanding about the commercial and long term operational benefits.
