Mixed I/O Module Configuration - Motorola ACE3600 RTU Owner's Manual

The Mixed I/O modules Analog-to-Digital conversion resolution is 16 Bit (including sign).
Each input is fully isolated from the other inputs on the module and also optically isolated
from the module internal circuits. The modules are fully calibrated. It is possible to test and re-
calibrate the module in the field.
The measured values are digitally filtered to reduce the 50 or 60 Hz noise. The user can select
the filtering frequency per module.
The measured values can be smoothed by digital filtering. Smoothing is accomplished by
calculating the running average values of a defined number of converted analog values
(samples). The user can select the level of smoothing per module. The higher the smoothing
level chosen, the more stable is the smoothed analog value and the longer it takes until the
smoothed analog signal is applied after a step response.
The user can select how the analog values are represented to the user application program, as
unitless numeric values or as scaled values that represent certain Engineering Units (EGU).
Each AI module can include an optional plug-in floating 24V DC power supply to power
external devices.
Each analog input has two Status LEDs:
•
UF - indicates Underflow when lit
•
OF - indicates Overflow when lit
The Mixed I/O modules support an optional 24V DC floating plug-in power supply (for
contact "wetting" or other purposes).
For a description of I/O module construction, location, LEDs, TB holder, and other common
I/O module features, see the I/O Modules chapter above. For details on Mixed I/O Module
specific parameters and configuration, see the Mixed I/O Module Configuration section below.

Mixed I/O Module Configuration

For configuration of the DIs, refer to the DI Module chapter.
For configuration of the DOs, refer to the DO/DI FET Module or DO Relay Module chapter.
For configuration of the AIs, refer to the AI Module chapter.
Sleep Mode
Each Mixed I/O module can be switched by the user application program to Sleep Mode. In
Sleep Mode, the module does not function and the power consumption is minimized. During
Sleep mode the user application program will get the predefined values per each I/O.
