Siemens 6ES7422-1BH11-0AA0 is a SIMATIC S7-400 digital output module for installed systems that switch 24-V-DC actuators through an isolated S7-400 output module. Siemens product data specifies 16 digital outputs, a 24 V DC load voltage and a rated current of 2 A per output at signal 1. This distinguishes the S7-400 module from versions with more channels but lower output current. The permitted load-voltage range is 20.4 to 28.8 V DC. Maximum no-load current from L+ is 30 mA, while maximum current consumption from the 5-V backplane bus is 160 mA. The outputs are electronically protected against short circuits, with a typical response threshold from 2.8 to 6 A. Siemens also documents maximum switching frequencies of 100 Hz with a resistive load and 10 Hz with a lamp load. Channels are electrically isolated in groups of 8 and from the backplane bus. The module measures 25 mm in width, 290 mm in height and 210 mm in depth, dissipates 5 W and weighs approximately 600 g. Before replacement, compare the full MLFB, load current, group wiring, fuse concept and STEP 7 configuration. The 16-channel, 2-A version must be distinguished from 32-channel, 0.5-A SM 422 variants in the S7-400-I/O family and from other 422 versions. Matching the channel groups, isolation, switching frequencies and protection behaviour helps retain the existing S7-400 actuator wiring and control-cabinet design.

Yes. This item is recorded as available stock and can be prepared for dispatch at short notice after the order is received.
Compare the complete order number, output version, channel and current class, existing engineering configuration and system environment with the installed module.
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.
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.
