DESCRIPTION:
The main functions of the No.1 board of regulator are changing the signal from direct, alternative, and frequency to the voltage form 0 to 5VDC.
The voltage signal regulator circuits include:
1) from 0~+30VDC single port input signal to 0~+5VDC output circuit, the number of the output circuit are 10;
2) from 0~+50VDC dual port input signal to 0~+5VDC output circuit, the number of the output circuit are 4;
3) from 0~+5VDC dual port input signal to 0~+5VDC output circuit, the number of the output circuit are 1;
4) from 0~+10VDC dual port input signal to 0~+5VDC output circuit, the number of the output circuit are 1;
5)from 2.5Vrms/125Hz alternative current input signal to 0~+5VDC output circuit, the number of the output circuit are 1;
