Analog Output Channel
Analog output can be either voltage output or current output.
The RGB LED colour will change from a cool colour of Blue, through Green and then bright Yellow showing that the analog output amplitude in the increasing order. -
Analog Input Channel
Analog input can be either voltage input, current input or resistive input.
The RGB LED colour will change from a cool colour of Blue, through Green and then bright Yellow showing that the analog input amplitude in the increasing order. When the analog input channel is configured as resistive input, and when the terminal is not terminated with any resistive load, or the wire is broken, the analog input channel detects a very high resistance, and will light up the RGB LED with pure RED colour signifying the analog channel is in error mode. -
