Siemens 6ES5464-8MC11 is a four-channel analog input module (AI 464) for SIMATIC S5 backplanes. Each of its four isolated input channels accepts DC voltages in the ±10 V range, providing galvanic isolation from the S5 CPU and backplane. This AI 464 module is designed for S5-90U, S5-95U, and S5-100U CPUs and is compatible with ET 100U and ET 200U I/O expansions. It is intended for monitoring DC voltage signals from sensors and transducers in legacy S5 installations.
