Multi-Rack Expansion Solution — SIEMENS 6ES7400-2JA10-0AA0 | SIMATIC S7-400
The SIEMENS 6ES7400-2JA10-0AA0 (IM 400-2) is the interface module that enables multi-rack configuration in SIMATIC S7-400 systems. Designed for process-critical environments where a single rack cannot accommodate all required I/O and function modules, this interface module extends the S7-400 backplane bus across multiple expansion racks — maintaining deterministic communication and system integrity at full rated speed.
At Konmask.com, we supply this module to MRO procurement teams, system integrators, and OEM machine builders who require verified, traceable components with fast lead times.
Where This Product Is Used
The 6ES7400-2JA10-0AA0 is specified in applications where the S7-400 CPU rack must be physically separated from or expanded with additional I/O racks:
- Chemical & Petrochemical Plants — Distributed I/O across hazardous-area cabinets; central CPU rack in safe zone with remote expansion racks in field enclosures.
- Power Generation & Utilities — Turbine control systems requiring high channel counts beyond a single rack’s capacity; boiler management with segregated analog and digital I/O racks.
- Automotive Assembly Lines — Body-in-white welding cells and paint shop conveyors where I/O density demands multi-rack S7-400 architectures.
- Water & Wastewater Treatment — SCADA-integrated pump station control with geographically separated rack segments in large pump halls.
- Steel & Metals Processing — Rolling mill drive coordination requiring dedicated I/O racks for drive interfaces, temperature measurement, and safety interlocks.
- Pharmaceutical Manufacturing — GMP-compliant batch control systems with validated S7-400 multi-rack configurations for segregated process areas.

Why Engineers Specify This Model
- Deterministic Multi-Rack Communication — The IM 400-2 maintains synchronous backplane bus extension, ensuring no latency penalty for I/O modules in expansion racks versus the central rack.
- Scalable Architecture — A single IM 400-2 in the central rack can drive up to 21 expansion racks (each fitted with a compatible IM 461-x receive module), supporting very large I/O counts without additional CPUs.
- Proven Long-Term Availability — The S7-400 platform has a documented long product lifecycle; the IM 400-2 is a stable, well-documented module with extensive installed base globally.
- Seamless STEP 7 / TIA Portal Integration — Fully configurable in SIMATIC STEP 7 (Classic) and TIA Portal with automatic rack topology recognition.
- Robust Industrial Design — Rated for 0–60 °C continuous operation; suitable for standard industrial cabinet environments without additional cooling.

Application-Specific FAQ
Q: Can the 6ES7400-2JA10-0AA0 be used with all S7-400 CPUs?
A: Yes. The IM 400-2 is compatible with all S7-400 CPUs (CPU 412 through CPU 417) when installed in the central rack. It is not compatible with S7-300 or S7-1500 platforms.
Q: What receive module is required in the expansion rack?
A: The expansion rack must be fitted with an IM 461-x series receive module (e.g., 6ES7461-1BA01-0AA0 for local expansion or 6ES7461-3AA01-0AA0 for remote expansion). The specific IM 461 variant depends on the required cable length and rack distance.
Q: How many expansion racks can one IM 400-2 support?
A: Up to 21 expansion racks in a segmented configuration, subject to the total I/O module count and power budget of each rack.
Q: Is this module configurable in TIA Portal?
A: Yes. The S7-400 hardware including the IM 400-2 is fully supported in TIA Portal V13 and later via the S7-400 hardware catalog. STEP 7 Classic (V5.x) is also fully supported.
Q: What is the cable type between IM 400-2 and IM 461-x?
A: For local expansion (same cabinet), a short ribbon cable is used. For remote expansion (separate cabinets), a shielded copper cable (SIEMENS 6ES7468-x series) is required, with maximum distances depending on the IM 461 variant selected.
Q: Do you offer exchange or repair services?
A: Yes. Konmask.com offers advance exchange for qualified accounts and can coordinate third-party repair for units with repairable faults. Contact us for details.
