Description
About the Fully modular connection
About the Fully modular connection
The Siemens SIMATIC TPA connection module (6ES7924-0CC20-0AA0) is a 3-tier screw-terminal interface for analog I/O modules on SIMATIC S7-1500 stations, without LED status indication. It accepts a 24 V DC rated / 50 V max supply at up to 1 A per signal cable, connects via a 16-pole IDC cable interface, and mounts on 35 mm or 15 mm DIN rail.

Selection Notes
The TPA designation is the analog-module connection block — use it instead of the TP2/TP1 digital-output blocks when wiring analog I/O, where the 3-tier, 30-terminal screw layout accommodates the extra reference and shield connections analog channels need. Screw terminals, versus push-in, suit installations where wiring needs periodic reconnection during commissioning or maintenance. Current per signal cable is capped at 1 A, half the digital TP2's 2 A rating, reflecting its analog signal-only duty.
Applications
Used as the field-wiring interface for analog input/output modules on SIMATIC S7-1500 stations within the TOP connect wiring system, in DIN-rail control cabinets requiring screw-terminal reconnection flexibility.

| marketing text | The TPA connection module for analog modules with screw terminals for 16-pin connecting cables without LED for signalling forms the interface between the connecting cables of the peripherals coming from the field and the SIMATIC S7-1500. This is mounted on the DIN rail and, thanks to its functionality with screw terminals, is exactly adapted to the respective task. This connection module is part of the fully modular SIMATIC TOP connect connection for the fastest and safest system cabling. In addition to low wiring costs, error sources in cabling can be significantly reduced. Sensors and actuators from the peripherals are combined with the connection modules of SIMATIC TOP connect and connected to the SIMATIC S7-1500 via cable and front plug-in module. |
