The Mitsubishi FX2N-4AD-PT is a specialized analog input module designed for the MELSEC FX series of programmable logic controllers. It provides a reliable and precise solution for temperature measurement by converting signals from up to four PT100 platinum resistance temperature detectors (RTDs). The module translates the analog resistance values into 16-bit digital data, which can be easily processed by the PLC’s main unit. This makes it an ideal component for industrial automation systems requiring accurate temperature monitoring and control, such as in process control, HVAC systems, and manufacturing environments. The module seamlessly integrates with the FX2N and other compatible PLC base units, expanding their I/O capabilities for temperature-sensitive applications.
