Solutions Handbook (AADvance Controller)
Time Stamp Accuracy 10ms
Safety accuracy limit 200µA for Analogue Inputs and 1.0V dc for Digital
Inputs.
Electrical Characteristics
Supply voltage Redundant 24V dc nominal, 18V dc to 32V dc range
Channel isolation (channel to channel
and channel to chassis)
Maximum withstanding ± 1.5kV dc withstand for one minute.
Power consumption, heat dissipation and weight depend on the arrangement of the
controller. You can estimate these values when you specify the controller using the
tables provided in this manual.
A typical module surface temperature measured against a processor module is 43°C ±
2°C.
Scan Times
The following scan times were taken from a test system consisting of production
modules.
Module Scan Time
T9401 Digital input module, 24V dc, 8 channel
Single
Dual
Triple 1.23ms
1.73ms
2.08ms
T9431 Analogue input module 24V dc, 8 channel
Single
Dual
Triple
1.26ms
1.91ms
2.33ms
T9451 Digital output module, 24V dc, 8 channel
Single
Dual
1.43ms
2.44ms
AADvance Workbench Sleep Period 57.2ms
Scan overhead per module 0.09ms
The tests did not measure the effect of logic complexity and communications loading.
The scan time is:
  (Number of module groups x scan time shown above) + Sleep Period + (Total
modules x scan overhead)
The scan time will vary by up to +/- 5ms (not including the effect of logic and
communications).
