Logical assignment of inputs for IMD1
IN1 = trigger
Quiescent level = High level Trigger start = Low/
High edge
IN2 = taring
Quiescent level = High level
High-Low-High pulse = taring (20 ms debounce
time)
Logical assignment of inputs for dosing (IMD2)
IN1 = BRK
IN2 = RUN
Quiescent level = High level,
High-Low-High pulse =
RUN
or
BRK
(20 ms debounce time)
The status of the inputs/outputs can also be loaded via the
RIO
? command.
Logical assignment of outputs for IMD0
OUT1/2 Low level
POR,Parameter1/2 = 0
OUT1/2 High level
POR,Parameter1/2 = 1
Logical assignment of outputs for IMD1/2
Low level
Function/output = inactive
High level
Function/output = active
The basic devices differ in the following functionality:
AED9101D basic device
Supports input IN1
AED9201B basic device
Supports inputs IN1, IN2 and OUT1...OUT6
AED9301B and AED9401A basic
devices
Support inputs IN1, IN2 and OUT1...OUT4
AED9501A basic device
Supports input IN1
The inputs/outputs of the AED9201B, AED9301B and AED9401A basic devices are electri
cally isolated.
