Acuvim-L
2.3.6 Digital Output (DO)
There are two digital outputs for Acuvim-L. For the Acuvim-BL, the terminals of
the digital output are DO1 , DO2 and DOC . For the Acuvim-DL/EL, the terminals
of the digital output respectively is DO11, DO12 and DO21, DO22.These two
digital outputs can be used as energy pulse output or over/under limit alarming
output.
Digital output circuit form is Photo-MOS. The simplified circuit is as below:
The max output voltage and current are 250Vac/300Vdc and 100mA.
When the digital output is used as over/under limit alarming output, the upper
and lower limit of the parameter, time interval and output port can be set from
the meter front.
2.3.7 Digital Input(DI)
There are 4 dry-contact digital input in extension modules respectively. The
digital input circuit can be used to detect remote signals, or be used as a counter
of input pulses.
