      Overview Manuals Common Applications Product Precautions
      The Siemens 6ES7288-3AR02-0AA0 is a SIMATIC S7-200 SMART EM AR02 RTD Input Module that provides two module-referenced RTD/resistance inputs with 0.1 degree temperature resolution.
      • EM AR02
      • 2 RTD or resistance-measurement inputs
      • 24 V DC; 20.4 to 28.8 V DC
      • 45 x 100 x 81 mm

      In an S7-200 SMART automation station, it measures two compatible RTD or resistance sensor circuits and provides 16-bit temperature or resistance data. It works with the exact CPU, expansion-bus or signal-board interface, wiring, field devices, and project configuration specified for the complete article number. It is applied in bearing, tank, heater, winding, and process temperature monitoring.

      Important Notice: Use the complete 6ES7288-3AR02-0AA0 code and verify the physical nameplate, current Siemens documentation, signal range, wiring, project, and accessories before installation or replacement.
