Mitsubishi Electric FX3U-16MR/ES Programmable Logic Controller Module

The Mitsubishi FX3U-16MR/ES is a 16-point DIN-rail mounted programmable logic controller (PLC) module designed for mixed digital I/O in small- to mid-scale automation tasks. Powered by 24 VDC, it provides digital DC inputs and both relay and transistor outputs, with moderate program memory suitable for compact control programs and expansion through FX3U expansion modules. It offers RS-232C and RS-485 communications (model dependent), features a fast instruction-processing CPU, and is IP20-rated with operating temperatures 0 to 55 °C and storage -25 to 75 °C. Common replacements include Mitsubishi FX3G-16MR/ES-A, Siemens S7-1200 6ES7212-1BB23-0XB0, and Allen-Bradley MicroLogix 1400 1766-LB16.
