RTU A200

Description



The A200 is Ami Tech's indigenously designed and developed Remote Terminal unit, which form the life line of the SCADA solution. A200 acquires, monitors and controls data related to breakers, isolators, transformers, transducers, etc., in a substation. The firmware of A200 interfaces with the main control centre using various communication protocols compliant with IEC 60870-5-101/104, MODBUS, DNP3 and SPORT. A200 is also compliant with IEC 61850, IEC 60870-5-103 and acts as a gateway for various IEDs.

A200 is a scalable, modular and configurable remote terminal unit used extensively for a wide variety of applications in power, transportation, water, etc. It is capable of monitoring both digital and analog data, communicating with and controlling remote systems. A non-proprietary, open architecture system with high in-built security, designed and developed to work in tropical environment.
