Product description

Siemens 6AG1 414-4HM14-4AB0 is a coated SIPLUS version of the CPU 414-4H for high-availability SIMATIC-S7-400H systems. It is based on the Siemens central processing unit 6ES7414-4HM14-0AB0. The module provides a total of 2.8 MB integrated RAM, divided equally into 1.4 MB program memory and 1.4 MB data memory. Communication is handled by a combined MPI/PROFIBUS DP interface, an additional PROFIBUS DP interface and two slots for optical synchronization modules. The CPU is therefore designed for redundant H systems in which two subsystems operate synchronously and plant availability is a priority. The SIPLUS variant has a protective coating and is specified by Siemens for ambient temperatures from 0 to +60 °C. An important engineering restriction applies: Siemens explicitly states that this exact order number is not approved for safety-related applications. It must therefore not be treated as a Safety CPU solely because of the S7-400H designation or characteristics of the base unit. The data sheet specifies firmware V4.5, typical current consumption of 1.4 A from the 5-V backplane bus and typical power loss of 6 W. For replacement or retrofit, the complete order number, hardware version, firmware, memory card, synchronization modules, PROFIBUS configuration and existing STEP-7 project should be checked together. The backplane supply, slot assignment and version of the IF-960 synchronization modules must also match the installed system. Properties of the successor must not be transferred to this type without verification. The series is discontinued; Siemens names 6AG1414-5HM06-7AB0 as its successor. For existing S7-400H systems, an exact type comparison remains essential because a generation change may require modifications to the hardware configuration, interfaces and redundancy architecture.

FAQ

Frequently asked questions

Contact us
What is Siemens 6AG1 414-4HM14-4AB0 designed for?

The SIPLUS CPU 414-4H is designed for high-availability SIMATIC-S7-400H systems. It has a protective coating and operates within the range of 0 to +60 °C according to Siemens.

Can 6AG1 414-4HM14-4AB0 be used in a safety-related application?

No. Siemens explicitly identifies this SIPLUS order number as not approved for safety-related applications.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.

Further details are provided in the terms and conditions supplied with your quotation.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
