Benefits
The digital input modules provide you with the following advantages:
• High channel density with low variety of parts, therefore less effort for ordering, logistics
and storage of spare parts
• Modules in 25 mm size without parameter assignment and diagnostics, therefore simple
commissioning
• Front connector in screw-type connection system or in push-in system (35 mm width) or
push-in system for 25 mm modules
• Same mechanical design, same handling and same accessories for all modules
• Same pin assignment for wiring, which means that circuit diagrams and wiring plans can
be universally used
• Any combination of narrow and wide modules
• Can be used centrally in SIMATIC S7-1500 and in the ET 200MP distributed I/O system
• Cost-effective implementation of simple counting tasks with two counter inputs each of
the high-feature modules DI16x24VDC HF and DI 32x24V DC HF
