Conditioned Buffer Outputs
Two outputs, one per channel, are provided via terminal pin connectors. These
outputs provide an ESD, EFT, and surge-protected replica of the signals that
are output to the local Expansion bus, and provided to any dynamic
measurement modules on the bus.
These signals are presumed to be 1/revolution.
1444-RELX00-04RB Relay Expansion Module
The relay expansion module has no analog outputs.
1444-AOFX00-04RB 4…20 mA Output Expansion Module
Four ESD- and EFT-protected outputs. Each output is a 4…20 mA
proportional signal that represents a selected measurement.
The outputs are not powered, require independent loop power, and are opto-
isolated from the module and each other.

services.
I/O Message Formats
Assemblies are created in Logix and defined by the 1444 Add-on Profile
(AOP) of the module. The AOP for the 1444 dynamic measurement module
creates assemblies for input, output, and configuration. The structure, content,
and meaning of the parameters of each of the assemblies, except configuration,
is provided in the following.
Input Assembly
The input assembly consists of four structures; three fixed Status data struc-
tures, and a variably defined data structure.
