The SIPLUS S7-1200 SM 1234 4AI/2AQ (model number: 6AG1234-4HE32-4XB0) is an analog input/output (AI/AQ) signal module manufactured by Siemens, designed for the SIMATIC S7-1200 series of programmable logic controllers (PLCs). This module is built upon the base model 6ES7234-4HE32-0XB0 and is protected with a conformal coating for reliable operation in extreme environmental conditions. It can operate stably within a wide temperature range of -20°C to +60°C. The SM 1234 module features 4 analog inputs (AI) and 2 analog outputs (AQ). For analog inputs, it supports either +/-10 V with 14-bit resolution or 0-20 mA with 13-bit resolution. This module is designed for processing and controlling analog signals and is used for measuring and controlling analog values such as temperature, pressure, and others. The module has a net weight of 0.198 kg and packaging dimensions of 8.70 x 10.50 x 5.50 cm.\n
