3.3 PCB No. 2132 (PD; Photo Diode, Pre-Amplifier, LED Relay)
PCB No. 2156 (PD2; Photo Diode, Pre-Amplifier, LED Relay)
3.3.1 Function
These PC Boards amplify the detector signal in channels CH1~CH6 and drives LEDs for these channels.
There are four kinds of boards (for CH2, 4, 6, for CH1, 3, 5, for CH1, 3, and for CH2, 4). Actually, this
board is used with composing two kinds of the board. (Refer to the table below.)
This circuit detects the scattered light on the channels CH1~CH4, the transmitted light on the channel CH5
on Detector Block (ATIII) and the transmitted light on the channel CH6 on Detector Block (Immunoassy),
amplifies by the current/voltage converter, and output to PCB No. 6362 (MAIN) or PCB No. 6373 (MAIN-2).
