Analog I/O terminals supply the values needed for precision control of a process including level, flow, and pressure data. Analog I/O signals come in ranges such as 0-20mA, 4-20mA and 0-10VDC. Protos X analog terminals are available in 12-bit resolution current, voltage, and 16-bit resolution temperature models with 2, 4 or 8 channels.

The Protos X compact, modular field I/O system
Allows a user to install remote field I/O devices without having to invest in another controller. The unique slim design and low cost of the Protos X I/O makes it the most practical distributed I/O available today. The ultra-slender form factor makes it easy to install on or near machine or application components, saving time and excess field wiring and speeding up troubleshooting. The ultra-compact design makes it perfect for applications where a typical PLC or I/O solution simply would not fit.
