General information about the multi inputs:
There are 4 digital inputs DI1 to DI4 available on the blue'Log base module, as well as 4 multi-inputs MI1 to MI4.
The 4 multi inputs MI1 to MI4 can be programmed as either analog or digital inputs.
Example:
MI1 - analog input -> connection of irradiation sensor (current signal 4-20mA)
MI2 - Analog input -> PT1000 temperature sensor connection (resistance)
MI3 - digital input -> counter input S0 signal
MI4 - Digital input -> Status input alarm transmitter from UPS
The digital inputs are mainly used for PowerControl tasks.
Example: Ripple control receiver connection
DI1 - active power 100%
DI2 - active power 60%
DI3 - active power 30%
DI4 - active power 0%
The digital outputs DO1 to DO4 can be used as feedback.
Additional 4 multi inputs and 4 digital outputs can be provided with the Multi IO expansion module.
