Ao (X1) - Motorola MOSCAD-M Owner's Manual

AO (x1)

One Analog Output is connected to TB5. The AO is 0-20mA or 0-5V. The AO type (current
or voltage) is determined by connecting to the proper pin on the TB and by selecting the
proper AO type in the software (either via the Configurator Hardware Test utility or the user
software application.)
The AO can be driven from an internal or external power supply. The minimum output
resistance for voltage is 5KΩ. The maximum output resistance for current is as shown below:
