The Siemens 6ES7288-3AR04-0AA0 is a 4-channel RTD input module for the S7-200 SMART PLC family, reading Pt100, Pt1000, Cu10, and Cu50 resistance thermometers at 16-bit resolution.
Powered from the 24V DC backplane supply with a tolerance of -15 / +20 %. The module draws 80 mA from the 5V backplane bus and 40 mA from the 24V field supply. At 150 g it adds no mechanical strain to the rail assembly.
The module has a 16-bit resolution across the analog input range.
Yes, it is a dedicated S7-200 SMART expansion module — the SM AR04 RTD — that snaps directly onto the backplane of any S7-200 SMART CPU.
Four analog inputs, all configurable for resistance thermometers (Pt100, Pt1000, Cu10, Cu50). No thermocouple support.
