Specifications and Product Details:

4 channel amp data metering, with 4 channel DI, 2 channel alarm output, RS485 comm port, especially for power station reconstruction project

Especially developed for indication and supervision of the three-phase circuit, replaces an analogical ammeter, reducing installation manpower and optimizing the used one of spaces in the panel.

Ideal for protection of three-phase networks is monitored and generally to own alarm superior and inferior. Protection of the parameters of programming by password.
