Description

[ez-toc]

Overview

Modified front connectors, called front connector modules, are available for connecting to the I/O modules of the SIMATIC S7-1500 and ET 200MP. These are plugged into the I/O module (35 mm design) to be wired instead of the front connector. The front connector modules are available in many different versions for digital and analog modules, and for 2 A digital output. The connecting cables are plugged into these front connector modules.

Design

Up to 4 connecting cables can be connected to the front connector modules for digital 16-channel or 32-channel modules with the 4 x 1 byte version. In the 1 x 4 byte connection version the connection is made with just one pre-assembled connecting cable. These are connected to the terminal modules.

A connecting cable with a 2-ampère terminal module in each case is connected to the front connector modules for 2-ampère output modules.

In the case of the front modules for the analog I/O modules there are versions got connection with four connecting cables (16 pole) or one connecting cable (50 pole).

The potential can be fed in at the terminal module or at the front connector module in the case of the 16/32 digital I/O modules:

Potential infeed via the front connector module with plugged-in jumper on the front connector module:

  • Max. current per double byte at 60°Celsius: 4 A
  • Max. current per double byte at 40 °Celsius: 6 A

Potential infeed via the front connector module without plugged-in jumper:

  • Max. current per byte at 60 °Celsius: 2 A
  • max. current per byte at 40 °Celsius: 3 A

If full current load is required, infeed must be implemented via the terminal modules. Potential infeed via the terminal modules without plugged-in jumper on the front connector module:

  • Max. current per byte at 60 °Celsius: 3 A
  • max. current per byte at 40 °Celsius: 4 A

Integration

For connection to the SIMATIC S7-1500 and ET 200MP I/O modules (35 mm version), the front connector module is plugged into the I/O module instead of the SIMATIC S7-1500 front connector. It has plugs for the connection of the connecting cables and 4 connections for potential infeed. For 16 and 32-channel I/O modules (24 V DC), a special version of the front connector module (digital 4 x 1 byte or 1 x 4 bytes) is used. For the digital output module (24 V DC/2 A), a special front connector module (2 A output) is used. For the analog I/O modules the front connector module with the terminal for 1 or 4 connecting cables is used.

Use in the case of SIMATIC S7-1500 and ET 200MP components

  • The front connector modules replace the SIMATIC S7-1500 standard connectors: 6ES7592-1AM00-0XB0 and 6ES7592-1BM00-0XB0
