Relay Operation & LED Display
Power around MICOM & Sensor Detector
1) The input AC voltage of DC-trans secondary registers 8V at CN10 between ①~③. The rectified
voltage passed through D101 ~ 104 becomes DC 5V through voltage regulator MC7805(REG1).
The power(DC5V) is supplied to the power around micom and sensor detector.
2) The input AC Voltage of DC-trans secondary registers 15V at CN10 between ⑤~⑦. The rectified
voltage passed throush D105 ~ D108 becomes DC 12V through voltage regulator MC7812CT
(REG2). The power (DC12V) is supplied to the relay operation and LED display.
It is designed for clock generation and time
calculation for synchronizing transmission and
reception on the logic elements inside the MICOM.
If the X-TAL specification changes, MICOM may
make an error.
(The standard components should be used.)
