Benefits
The digital output 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
●
High feature module DQ 8x24VDC/2A HF: You can use pulse width modulation (PWM) to
easily generate periodic pulses with a constant rated voltage and a variable pulse
duration.
Typical use:
–
Control of proportional valves and way values (e.g. energy saving by reducing the
holding current).
–
Heating control e.g. via an external additional power unit.
