Peripherals
22
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.
