insulated digital output (contact) channels is installed in DIO board. A 4 channel analog input
circuit, which converts 4~20mA input signal to voltage and convert the voltage to digital signal
using differential amp, and an analog output circuit, which generates output voltage from 0 to 10V
using DA converter, are installed in AIO board.
*Optical conversion board
Optical/Electrical signal conversion circuit that can reduce the noise effects between the main
control part and the power cell control part and optical cable connector are installed in optical
conversion board. Optical conversion circuit guarantees 5Mbps communication speed for CAN
communication.
* Power cell control board
Power cell control board performs PWM for IGBT and generates phase differences in accordance
with the control command from main control part. It also contains protective ground detection
circuit. Communication control circuit for CAN communication, optical conversion circuit, serial
communication control circuit for program download and PC connection port for individual power
cell test are installed in the board.
