Product description
Siemens 6ES7 432-1HF00-0AB0 is an SM 432 analog output module for the SIMATIC-S7-400 family. It is intended for existing S7-400 stations that require analog manipulated variables, setpoints or actuator control and where the installed module must be replaced by the exact MLFB. The Siemens module data manual identifies this version as AO 8 x 13 Bit with eight outputs. Each channel can be configured individually for a voltage or current signal, including voltage ranges such as 0 up to 10 V and ±10 V as well as current ranges such as 4 up to 20 mA. For service work, it is important that the electronics and nominal load voltage use 24 V DC, that the outputs are wired through L+/M and MANA, and that the analog section is isolated from the CPU and backplane bus. The documented dimensions of 25 x 290 x 210 mm and weight of approx. 650 g support comparison with the installed rack and control-cabinet documentation. Further technical data include typical power dissipation of 9 W, a shielded cable length of up to 200 m and 13-bit resolution with defined conversion times and output-load limits. When selecting a replacement, compare the exact Siemens order number, channel count, signal type, output ranges, isolation, connector assignment and STEP-7 hardware configuration. For spare-parts matching, Siemens 6ES7 432-1HF00-0AB0 should also be checked against the installed S7-400 project. These details distinguish the module from digital output modules, analog input modules, communication modules and CPUs in the same system family.

What is Siemens 6ES7 432-1HF00-0AB0 used for?
The SM 432 analog output module is used in SIMATIC S7-400 systems that require eight analog output channels for voltage or current signals.
Which output ranges does the SM 432 AO 8 x 13 Bit support?
The Siemens manual specifies voltage ranges of 1 up to 5 V, 0 up to 10 V and ±10 V, and current ranges of 0 up to 20 mA, 4 up to 20 mA and ±20 mA.
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.
