Digital output (only MIB 7020)
Digital output (DO)
There are two digital outputs in the MIB 7020. The terminals of the digital
outputs DO1, DO2 and DOC are 14, 15 and common 16. These two digital
outputs can be used as energy pulse output or limit alarming outputs.
Digital output NE (normally energised), NC (normally closed), circuit form is
Photo-MOS. The simplified circuit is as shown below:
The contact is closed (NC) when no alarm is present.
The max. output voltage and current are 250V AC/300V DC and 50mA.
When the digital output is used as over/under limit alarm output, high/low
limit and alarm time can be set in the system parameter settings.
The wire of the digital output should be 0.5-1.5mm² (AWG16-22).
