Siemens 6ES7123-1JA00-0AB0 Digital Input Module

Siemens 6ES7123-1JA00-0AB0 is a SIMATIC SC electronic submodule that provides a single analog input channel for RTD sensors, supporting Pt100 and Ni100 configurations with a rated input range of 0 to 600 ohms. The input impedance is 1 MΩ, and the signal path is isolated from the power supply and backplane with up to 1500 V AC, enabling safe operation in industrial environments. The module measures 10 mm in width, 64 mm in height, and 51 mm in depth and weighs approximately 20 g. Typical conversion cycle time per channel is 110–130 ms. Designed for integration into SIMATIC SC systems, this submodule is commonly used for temperature monitoring in process control, HVAC, and equipment instrumentation where RTD sensors are employed.
