SIEMENS 6ES7403-1JA01-0AA0 SIMATIC S7-400, extension rack ER2 with 9 slots
Okay, let's take a look at the Siemens 6ES7403-1JA01-0AA0 SIMATIC S7-400, ER2 Expansion Rack:
This is another model of the expansion rack for the Siemens SIMATIC S7-400 programmable logic controller (PLC) system. Like the previous 6ES7403-1JA01-0AA0 ER2 rack, this version is used to add additional I/O and other modules to an existing S7-400 configuration.
The key features of the 6ES7403-1JA01-0AA0 ER2 expansion rack include:
- Ability to hold up to 9 modules in the S7-400 series
- Dimensions of 482.6 mm x 350 mm x 180 mm (W x H x D)
- Supports redundant 100-240 VAC/DC power supplies
- Includes a system bus to connect the modules within the rack
- Mounts on a standard 19" rack system
- Allows expansion of an existing S7-400 PLC system by adding more I/O, communication, or other modules
The main difference between this model and the previous 6ES7403-1JA00-0AA0 is that this 6ES7403-1JA01-0AA0 ER2 rack has an updated design or feature set compared to the earlier version. However, the core functionality of providing modular expansion for an S7-400 PLC system remains the same.
Like the previous ER2 rack, this model connects to the main S7-400 central rack via a bus connector, enabling seamless integration of the expansion rack's modules into the overall SIMATIC S7-400 control system architecture. Let me know if you need any other details on this specific S7-400 expansion rack.
