The LOGO! AM2 RTD (6ED1055-1MD00-0BA2) is an analog expansion module from Siemens, designed for LOGO! 8 systems, operating with a 12/24 V DC power supply. The module provides 2 analog inputs (AI, for Pt100/1000 sensors, temperature range -50…+200 °C). With a net weight of 0.128 kg and packaging dimensions of 7.30 x 9.90 x 5.70 cm, its compact design helps save space in control cabinets. DIN rail mounting is supported. This module is used in LOGO! 8 control systems for small to medium-sized automation projects, such as managing heating, cooling, or climate control systems by reading data from temperature sensors (Pt100 or Pt1000). Its ease of programming and flexibility make it widely used in small industrial and commercial applications.
