System overview
3.6 Input and output modules
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 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
