SIMATIC S7-1500, digital input module DI 32x24 V DC HF, 32 channels in groups of 16; of which 2 inputs as counters can be used; input delay 0.05..20 ms input type 3 (IEC 61131); diagnostics; hardware interrupts: front connector (screw terminals or push-in) to be ordered separately 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. The scalable configuration of an ET 200MP station is ensured by the wide range of signal modules. A large number of digital and analog input and output modules are available. This ensures the universal applicability of the system.
