Siemens 6ES7288-3AR04-0AA0 EM AR04 4-Channel RTD Input Module
A four-channel EM AR04 module for RTD temperature and resistance measurements in S7-200 SMART systems.
Product Profile
PROFILESiemens 6ES7288-3AR04-0AA0 is the SIMATIC S7-200 SMART EM AR04 expansion module with four 16-bit RTD input channels. It supports documented resistance-temperature sensors and resistance measurement through two-, three- or four-wire circuits.
The four-channel AR04 identity must not be confused with the two-channel AR02 or with the later G2 article suffix. The installed label and project channel map establish the exact spare boundary.
Internal calibration and diagnostics support controlled commissioning, including overflow, underflow, wire-break and low-supply recognition.
Technical Data

FAQ
QUESTIONSQ01Can 6ES7288-3AR04-0AA0 use the two-channel AR02 project map?
No. 6ES7288-3AR04-0AA0 has four inputs, so hardware identity, addressing and channel configuration must follow AR04 records.
Q02What distinguishes 6ES7288-3AR04-0AA0 from a G2 AR04 article?
The complete suffix is different. Do not treat 0AA0 and a later G2 suffix as interchangeable without Siemens compatibility evidence.
Q03What wiring evidence should accompany 6ES7288-3AR04-0AA0?
Provide all four sensor types, two-/three-/four-wire diagrams, shield practice, cable lengths, ranges and terminal photographs.
Q04How should wire-break behavior be checked on 6ES7288-3AR04-0AA0?
Use the approved controlled test for each configured channel and confirm the expected diagnostic and process fallback response.
Q05What belongs in the 6ES7288-3AR04-0AA0 acceptance report?
Record startup calibration completion, four reference results, units, alarm limits, diagnostic tests, 24 V supply and final project identity.
