Product Summary

Siemens 6ES7288-3AR04-0AA0 is a EM AR04 RTD analog input expansion module for the SIMATIC S7-200 SMART / EM AR04 platform. It is intended for industrial automation projects that require a precisely matched Siemens order number, documented signal configuration and reliable maintenance planning. The module supports four rtd input channels with 16-bit conversion. Procurement teams should use the complete part number rather than a shortened family name. Before ordering, confirm the installed hardware and firmware status, connector or BaseUnit arrangement, engineering project, field wiring and required operating functions. Availability is quotation-based, and the supplied condition and one-year warranty will be confirmed in writing.

Key Product Information

RTD Temperature Measurement

The EM AR04 module converts resistance-temperature-detector signals into digital values for the connected SIMATIC SMART station. Reliable results depend on the configured sensor type, wiring method, conductor compensation, channel scaling and installation environment. Confirm the complete order number and the target CPU or IM60 station before procurement.
