BJ-194Z is a high-end multifunction power meter manufactured by Blue Jay. It is the ideal choice for monitoring and controlling of power distribution systems. With its four direct access keys and LCD displays, helps you use all the parameters in 3P3W or 3P4W LV installation. It can be used as a data gathering device for an intelligent Power Distribution System or Plant Automation System. All monitored data is available via a digital RS485 communication port running Modbus-RTU Protocol. Ethernet communication are also options.
