SIPLUS S7-1200 SM 1231 4AI based on 6ES7231-5ND32-0XB0 with conformal coating, -20.+60°C, analog input, SM 1231, 4 AI, +/-10V, +/-5V, +/-2.5V, +/-1, 25 or 0-20mA/4-20mA, 15 bit+sign bit SIMATIC S7-1200 Basic Controller - flexible thanks to a wide range of communication options. With signal modules, you can adapt the configuration of your SIMATIC S7-1200 (except CPU 1211C) to suit your individual requirements. A range of digital and analog input, output and mixed modules is available for this purpose, including fail-safe versions. This fine-grained design option saves you space in the control cabinet and optimizes your hardware costs. Like the CPU, the analog input modules are also protected against extreme environmental conditions. Thanks to the 100% conformal coating, they can withstand biological, chemical and mechanically active substances, condensation, frost and harmful gases. No matter what the conditions - your analog signals are reliably recorded.
