SIEMENS S7-300 SM 323/SM 327 digital input/output modules
Digital inputs and outputs
For connection of switches, 2-wire proximity switches (BEROs), solenoid valves, contactors, low-power motors, lamps and motor starters
The digital input/output module features the following mechanical characteristics:
Green LEDs for indicating the signal states on the inputs/outputs,
Plug-in option for the front connector
Labeling field on the front door
Connector pin assignment for the wiring on the inside of the front door.
There are no slot rules, the addresses of the outputs are determined by the slot.
When used in ET 200M in combination with active bus modules, hot swapping is possible without any reaction.
The digital input/output modules convert
the level of the external digital signals from the process to the internal signal level of the controller and
the internal signal level of the controller to the external signal level required by the process.
The SM 327 is an additional finely scalable IO module. It has a total of 16 channels, whereby 8 channels are permanently defined and a further 8 channels can be used individually as inputs or outputs. This hybrid module can therefore be flexibly implemented for any combinations.
