CHAPTER 3: CONNECTING TO DEVICES AND NETWORKS
Peripherals
Peripheral I/O modules are intelligent modules containing an on-board microprocessor.
They are configured as slaves to the D20MX processor board. In this way, specific I/O
processing is distributed throughout the RTU to the appropriate I/O module.
There are five types of I/O peripherals:
• D20A analog input
• D20S digital inputs
• D20K digital output
• D20C combination input/output
• D20AC alternating current analog input
Optional high-voltage peripherals are also available.
The D20MX is only compatible with certain peripheral common code (i.e., pcommon)
versions as defined in
Table 13.

Repeaters
Repeater and extension modules can be used to extend the distance between peripheral
modules.
• D.20 Communication Interface: 520-0117.
• D.20 Fiber Optic Splitter 4-way: 520-0118.
• D.20 GFO: 520-0148.
