Siemens LOGO! AM2 RTD Expansion Module (6ED1055-1MD00-0BA2)
Siemens LOGO! AM2 RTD Expansion Module (6ED1055-1MD00-0BA2) is an analog temperature input expansion module for LOGO! 8 controllers. Operating on 12/24 V DC, it provides 2 RTD analog inputs for Pt100 and Pt1000 sensors, enabling accurate temperature measurement in industrial and building automation systems across the UAE.
The Siemens LOGO! AM2 RTD Expansion Module (6ED1055-1MD00-0BA2) is designed to extend the temperature measurement capabilities of Siemens LOGO! 8 basic units. Powered by 12 V or 24 V DC, this module enables precise acquisition of temperature data using Pt100 and Pt1000 resistance temperature detectors (RTDs).
The module provides 2 analog RTD input channels with support for 2-wire or 3-wire connections, allowing flexible integration of temperature sensors in automation systems. It supports a temperature measurement range of approximately -50 °C to +200 °C, making it suitable for HVAC, industrial process monitoring, and building automation applications.
Designed exclusively for resistance thermometer inputs, the LOGO! AM2 RTD does not support voltage or current signals, ensuring optimized accuracy and stability for temperature measurement tasks. Its compact DIN-rail design allows easy installation and efficient use of space in control cabinets.
