Ruggedized RTD input for the LOGO! 8
The 6AG1055-1MD00-7BA2 is the SIPLUS variant of the standard LOGO! AM2 RTD (6ED1055-1MD00-0BA2), built for environments where the standard part would trip on temperature alone. That makes it a candidate for unheated enclosures, cold stores, or outdoor cabinets where the standard LOGO! expansion would be out of spec.
Two Pt100/Pt1000 inputs, 12/24 V DC supply
The module provides two analog inputs for resistance thermometers, accepting Pt100 or Pt1000 sensors in 2- or 3-wire connection. Supply range is 10.8 V DC to 28.8 V DC, covering both 12 V DC and 24 V DC control buses. Typical current draw is 30 mA — negligible for the LOGO! backplane budget, but worth confirming if the power supply is already loaded with other expansion modules. The IP20 housing means it belongs inside a panel or enclosure — no washdown exposure. The altitude derating is documented: full temperature range up to 2 000 m, then -10 K above that, -20 K above 3 500 m, with a hard ceiling at 5 000 m.
