POINT I/O Module Data
These POINT I/O modules produce one byte of input data (scanner Rx). They
do not consume I/O data (scanner Tx).
Digital Output Modules
Read this section for information about digital output modules.
Digital DC Output Modules
The features of DC output modules include the following:
•
24V DC outputs with a range of 10…28.8V dc
•
Output diagnostic features are incorporated to assist in troubleshooting
•
Current limited outputs of up to 2 A with respect to their DC return
•
Autobaud (will match baud of existing devices on the network)
•
Sequential auto addressing
I/O messages are sent to (consumed) and received from (produced) these
POINT I/O modules. These messages are mapped into the processor memory.

These POINT I/O modules produce one byte of input data (scanner Rx). They
consume one byte of output data (Scanner Tx).
