Automation System and Bay Control Unit

APPLICATIONS Substation Automation: Acquisition, monitoring and measurement unit for any bay position.

Sequential event logger: It stores input and output change of status with an accuracy of 1 millisecond.

Great interoperability capacity among devices through conventional protocols and/or IEC 61850 standard

protocols using Ethernet or serial ports.

Auxiliary service monitoring and control.

KEY BENEFITS IEC 61850 native design.

Robust and reliable equipment, allowing its use both in process bus applications and station bus.

Interoperability with the main IED manufacturers. Flexibility for the implementation of advanced control strategies to get the most of the communication capacity performance and the IEDs’ current interoperability.

IEEE 1588 Synchronization, PRP Network Redundancy and IEC 61850 Test Mode.

Modularity, which allows the selection of the most suitable hardware configuration.

Visual logical configuration in accordance with IEC 61131 standard.

It optimises the implementation of any monitoring system by selecting previously configured single diagram lines and adapting them to your needs through the saTECH CNF configuration software, in an easy and simple way.
