Analog Output (AO) Setup

Analog outputs can be 0 to 10 V
they can be 0 to 100% duty cycle PWM outputs. They
usually come preprogrammed from the factory. An
analog output is wired to a physical pin, either PWM or 10
bit D/A. The source for an analog output can be mapped
from several places including mapping an analog input to
an output.
Analog Voltage Channels
Channel ID 1 maps to connector pin BS3-9
•
Channel ID 2 maps to connector pin BS3-10
•
Analog PWM Channels
Channel ID 3 maps to connector pin BS2-15
•
Channel ID 4 maps to connector pin BS2-16
•
Channel ID 5 maps to connector pin BS2-17
•
Channel ID 6 maps to connector pin BS2-18
•
Channel ID 7 maps to connector pin BS2-19
•
Channel ID 8 maps to connector pin BS2-20
•
Channel ID 9 maps to connector pin BS2-21
