Overview Manuals Specifications Application Communication Safety & Compliance

Features:

  • Designed for S7‑400H and S7‑400F/FH systems with two sync module interfaces, enabling seamless failover for mission‑critical processes
  • 1.4 MB work memory (700 KB program + 700 KB data), 0.06 µs bit operation performance, and support for expandable load memory up to 64 MB via FLASH or RAM cards
  • Offers MPI/DP and PROFIBUS DP interfaces, supporting up to 32 connections on MPI and 32 DP slaves, plus PG/OP and S7 communication services
The 6ES7414-4HJ04-0AB0 is engineered for applications where downtime is not an option. As a dedicated CPU for S7‑400H systems, it works in pairs with two fiber‑optic synchronization modules (6ES7960‑1AA04‑0XA0) connecting the primary and standby CPUs . If the primary CPU fails, the standby unit takes over without process interruption—critical for chemical plants, power generation, or any continuous process where a controller failure could cause production loss or safety hazards.

At the heart of this CPU lies a high‑speed processor capable of executing bit, word, and fixed‑point operations in just 0.06 µs, with floating‑point math taking only 0.18 µs . The 1.4 MB work memory (700 KB for program, 700 KB for data) provides ample space for large control programs. When more storage is required, the load memory can be expanded up to 64 MB using either FLASH (FEPROM) or RAM memory cards .

The 6ES7414-4HJ04-0AB0 comes equipped with four communication interfaces: one MPI/DP port, one PROFIBUS DP port, and two dedicated slots for sync modules . The MPI/DP interface (X1) supports PG/OP communication, routing, and S7 communication at speeds up to 12 Mbit/s, and can serve either as an MPI network or as a PROFIBUS DP master controlling up to 32 DP slaves . The second DP interface provides additional PROFIBUS DP master capability, effectively doubling the I/O capacity and allowing flexible system distribution.

The 6ES7414-4HJ04-0AB0 Siemens High-Performance Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Manufacturer Siemens
  • Model 6ES7414-4HJ04-0AB0
  • Condition New Original ready stock
  • Product Family 6ES5374-1KH21,6ES5316-8FA12,6ES5312-3AB31,6ES5535-3LB12
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Chemical & Petrochemical Processing: Manages continuous production processes, distillation columns, and hazardous chemical formulation where safety shutdowns must be avoided through active hardware redundancy.
  • Oil & Gas Infrastructure: Regulates offshore drilling platforms, cross-country pipelines, and pumping stations requiring fault-tolerant, isolated control loops.
  • Power Generation & Utilities: Controls boiler control systems, steam/gas turbine operations, and regional water treatment facilities that demand un-interrupted operation.
  • Interface 1 (MPI / PROFIBUS DP Master): An RS-485 serial interface operating at speeds up to 12 Mbit/s. It is used for connecting programming consoles (PG/PC), Human Machine Interfaces (HMI panels), or a small network of downstream PROFIBUS slaves.
  • Interface 2 (Dedicated PROFIBUS DP Master): A standalone, high-speed RS-485 interface operating at up to 12 Mbit/s. It functions as a dedicated deterministic line to map decentralized I/O networks (such as SIMATIC ET 200M sub-racks) to the CPU processing table.
  • Interfaces 3 & 4 (Synchronization Module Slots): Two dedicated plug-in ports built specifically to accommodate IF 960 fiber-optic synchronization submodules. These fiber-optic links directly cross-connect two identical 414-4H CPUs in an S7-400H configuration.
  • Explosion Proofing (Hazardous Locations): Carries international explosion safety certificates including ATEX (DEKRA) for European hazardous zones, and FM (Factory Mutual) Approvals for North American installations (e.g., FM17US0117X). This qualifies the S7-400 system for mounting inside control enclosures operating near potentially explosive atmospheres.
  • General Industrial Conformity: Bears the CE Mark and complies with the IEC 61131-2 structural baseline, certifying that its physical architecture withstands standard factory vibration, electromagnetic interference (EMC), and electrical line transients.
