DIAGNOSTICS, PROTECTION & INSTALLATION

Temperature measurement expansion for S7-200 SMART systems

The EM AR04 adds dedicated resistance-temperature acquisition to a compact S7-200 SMART controller. It is suited to engineering work that requires consistent sensor wiring, channel documentation and controlled commissioning without mixing temperature signals with general-purpose analog channels.
