RELIANCE S-D4008-A / S-D4008 Analog I/O Module – AutoMate Series
When an analog I/O module fails on the production floor, the consequences are immediate and costly: process variables go unmonitored, feedback loops break down, and entire automated lines can grind to a halt. In continuous-process industries—chemical plants, paper mills, metal processing facilities—even a brief loss of analog signal integrity can trigger emergency shutdowns, product waste, and unplanned downtime measured in thousands of dollars per hour. The RELIANCE S-D4008-A (also referenced as S-D4008) is the precision component that keeps those critical analog signals flowing reliably.
Within the Reliance Electric AutoMate programmable controller family, the S-D4008-A occupies a key position as a dedicated analog I/O module designed to interface real-world process signals with the AutoMate CPU. Reliance Electric—later absorbed into Rockwell Automation—built the AutoMate series to serve heavy industrial environments demanding high noise immunity and long service life. The S-D4008-A continues to be a sought-after replacement and spare part in legacy AutoMate installations worldwide, particularly in North American and European manufacturing plants that have standardized on this platform for decades.
