SIPLUS S7-1500 DI 16x230V AC BA -40...+70°C with conformal coating based on 6ES7521-1FH00-0AA0 . Digital input module DI 16x230 V AC, 16 channels in groups of 4 Input delay 20ms Input type 1 (IEC 61131) The SIMATIC ET 200MP is a modular and scalable I/O system with IP20 for universal use, and offers the same system advantages as the S7-1500. It permits the shortest bus cycle times and fastest response times, even with large volumes of data. The distributed I/O system is particularly easy to install, wire, and commission. Thanks to its scalable design, you can gear the IO station exactly to the on-site requirements. Just like the CPU, the digital input modules are also protected against extreme ambient conditions. Due to the 100% conformal coating they can withstand biologically, chemically and physically active substances, condensation, frost, and corrosive gases. Regardless of the conditions, your digital signals are reliably recorded.
