Gillam Your best partner for customized solutions



USC is a modular Remote Terminal Unit with Programmable Logic Controller designed for power grid automation. USC offers highly flexible communication gateway to interoperate easily with your various substation fieldbus IED. Soft PLC allows programmable automation of local I/O and remote fieldbus information. USC supports flexible, redundant communication to your SCADA. You can also take advantage of the USC local computation ability and measurement archiving before transmitting your realtime data.

USC built-in cyber resilience is designed to keep your critical application safe of cybersecurity concerns.

The USC is specifically designed for power grid automation.

Embedded WEB server and optional touchscreen provide intuitive maintenance information.

Consultation of measurement archives through integrated graph analyzer tool.
