|marketing text|The TPA connection module for analog modules with screw terminals for 16-pin<br>connecting cables without LED for signalling forms the interface between the<br>connecting cables of the peripherals coming from the field and the SIMATIC<br>S7-300. This is mounted on the DIN rail and, thanks to its functionality with<br>screw terminals, is exactly adapted to the respective task. This connection<br>module is part of the fully modular SIMATIC TOP connect connection for the<br>fastest and safest system cabling. In addition to low wiring costs, error sources<br>in cabling can be significantly reduced. Sensors and actuators from the<br>peripherals are combined with the connection modules of SIMATIC TOP<br>connect and connected to the SIMATIC S7-300 via cable and front plug-in<br>module.|||
