Machine temperature monitoring
Connects compatible RTDs for bearing, enclosure or process-temperature supervision.
Siemens 6ES7288-3AR02-0AA0 is the SIMATIC S7-200 SMART SM AR02 expansion module for two resistance-temperature or resistance measurement channels.
Siemens 6ES7288-3AR02-0AA0 is the SIMATIC S7-200 SMART SM AR02 expansion module for two resistance-temperature or resistance measurement channels. The module is intended for applications that bring compatible Pt, Ni, Cu or resistance signals into an S7-200 SMART controller for monitoring and control. Siemens specifies sigma-delta conversion, configurable integration times and selectable interference suppression for industrial measurement environments. The module is appropriate for maintenance, panel upgrades and machine-temperature monitoring where two RTD channels are required. Before ordering, confirm the complete article number, sensor type, resistance range, wiring method, controller configuration, module revision and available expansion position.

Connects compatible RTDs for bearing, enclosure or process-temperature supervision.
Supplies two measured temperature values to an S7-200 SMART control sequence.
Accepts supported resistance ranges for appropriate industrial sensing circuits.
Supports replacement of an existing AR02 after sensor type, range and wiring verification.
Select the correct RTD or resistance type in the controller project before commissioning. De-energize the panel, follow the official wiring diagram, route sensor cables away from power conductors and verify the configured integration and interference-suppression settings for the installation environment.
Match the complete article number 6ES7288-3AR02-0AA0. Confirm the controller model, expansion position, channel configuration, signal range, terminal assignment and installed module label. Hardware revision, available unit details and any project-specific compatibility requirement must be confirmed before ordering.
Siemens lists supported Pt, Ni, Cu and resistance measurement configurations; select the exact type in the project.
The SM AR02 provides two resistance-temperature or resistance input channels.
