General
The Banner Engineering S15C-3CT20A-MQ-1 is an industrial three-phase AC current monitoring converter designed to measure electrical current using external current transformers. It supports current monitoring up to 20 A and converts the current transformer signals into digital Modbus data for integration with PLCs, controllers and industrial monitoring systems.

Part of Banner Engineering's S15C Series, this compact in-line converter operates on a 10–30 V DC supply and communicates through Modbus. Its integral M12 quick-disconnect connectors and IP65, IP67 and IP68 environmental protection ratings make it suitable for industrial electrical condition-monitoring applications.
