Peripherals<br />
CHAPTER 1: BEFORE YOU START<br />
Peripheral I/O modules are intelligent modules containing an on-board microprocessor.<br />
They are configured as slaves to the <strong>D20MX</strong> processor board. In this way, specific I/O<br />
processing is distributed throughout the RTU to the appropriate I/O module.<br />
There are five types of I/O peripherals:<br />
• D20A analog input<br />
• D20S digital inputs<br />
• D20K digital output<br />
• D20C combination input/output<br />
• D20AC alternating current analog input<br />
Optional high-voltage peripherals are also available.<br />
