Siemens 6ES7422-1BL00-0AA0 is a SIMATIC S7-400 digital output module for controlling 24-V-DC actuators in industrial automation systems. It provides 32 electrically isolated digital outputs. Each output has a rated current of 0.5 A and an admissible range from 5 mA to 0.6 A. Load voltage L+ is 24 V DC, with a permissible range from 20.4 to 28.8 V DC. Typical power loss is 4 W. Maximum current consumption is 30 mA from L+ without load and 200 mA from the backplane bus. The module supports lamp loads up to 5 W, switching frequencies up to 100 Hz with resistive loads and shielded cable lengths up to 1000 m. Its outputs are isolated as one group of 32 and from the backplane bus. Dimensions are 25 x 290 x 210 mm, and the approximate weight is 600 g. This channel density is useful where many 24-V actuators are switched from a single S7-400 rack. Before replacement, compare the full MLFB, output count, current class, isolation arrangement, load supply, wiring and STEP 7 configuration. Siemens 6ES7422-1BL00-0AA0 is intended for direct matching with an installed output level, not as a generic substitute for another SM 422 variant.

If a fault occurs within 14 calendar days, please contact us in writing. Depending on availability, we will either provide a replacement or refund the full purchase price after the item has been returned. Further details are set out in the terms and conditions supplied with our quotation.
We normally dispatch available items immediately and, in many cases, on the same working day. For urgent requirements or machine downtime, we will identify the fastest suitable option and can confirm a specific delivery window on request. Express shipping and collection from our premises are also possible by arrangement. We ship worldwide using reliable parcel and freight carriers; freight shipments may require additional preparation to ensure safe delivery.
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.

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.
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.
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.
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.
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.
