Using electrical parameters means using several analog or digital single-function products such as ammeters, voltmeters or watt meters. BJ194E-9SY, with its four direct access keys and LCD displays, helps you use all the parameters in 3P3W or 3P4W LV installation. These parameters can be centralized on a PC or PLC through an RS 235 link using MODBUS protocol. The casing is designed so that the installer can easily fit the meter to the door of a cabinet. To facilitate and optimize the operators work, the BJ194E uses one of the most functional principles for integrating communications or metering.
