Introductions

1.1. Function Specification

IM300 is an intelligent multipurpose power parameter monitoring and control
device which has an extensive range of applications in 6~35kV or 0.4kV power
systems. It has the data acquisition, control and statistical functions, such as electrical
parameters measurement, calculation and statistics, fault records, 2 ~ 31st
harmonics monitoring function, 4-ch digital inputs and 2-ch relay outputs, 1-ch
4~20mA DC transmission output, over-limit alarm and other functions. IM300 is
equipped with RS485 communications and MODBUS-RTU protocol for integration
into any power monitoring and control system. The appearance is shown in fig 1.1.1.
