Overview
The 6ES7455-0VS00-0AE0 is a Siemens FM 455 controller module, a dedicated analog control processor for the S7-400 platform. It provides 16 analog inputs configurable for thermocouples (types B, J, K, R, S), Pt 100 RTDs, or voltage/current signals, plus 16 analog outputs, all on a single-wide module drawing 17.3 W from a 20 V DC supply.
Applications
The FM 455 is used in continuous process control loops — temperature, pressure, flow, and level — where a dedicated analog controller is preferred over CPU-based PID. Typical installations include chemical reactor temperature profiling, furnace zone control, and multi-loop heat exchanger regulation within a Siemens S7-400 rack.
