SIMATIC S7-300 I/O ModulesSignal modules are the interface of the SIMATIC S7-300 to the process. A host of different digital and analog modules provide exactly the inputs/outputs required for each task. Digital and analog modules differ as regards the number of channels, voltage and current ranges, electrical isolation, diagnostics and alarm functions, etc. |  |
In all the module ranges named here, SIPLUS components are also available for extended temperature range -25...+60°C and aggressive atmosphere/condensation.
Easy installation
The sensors/actuators are connected through front connectors. When a module is replaced, the connector is simply plugged into the new module of the same type; the wiring is retained. The coding of the front connector avoids mistakes.
Fast connection
Connection with SIMATIC TOP connect is even simpler and faster (not for the onboard I/O of the compact CPUs). Preassembled front connectors with single cores and a complete plug-in modular system comprising a front connector module, connecting cable and terminal block are available.
High packing density
The high number of channels on the modules provides for the space-saving design of the S7-300. Modules are available with 8 to 32 channels (digital) or 2 to 8 channels (analog) per module.
Simple parameterization
The modules are configured and parameterized using STEP 7, and there are no inconvenient switch settings to be made. The data are stored centrally and, following module replacement, they are automatically transferred to the new module so that no setting errors can occur. No software upgrade is required when using new modules. A configuration can be copied as often as required, e.g. for standard machines.
