Product description

Siemens 6ES7 422-1BH10-0AA0 is a digital output module SM 422 for the SIMATIC S7-400 automation system. It provides 16 outputs for 24-V-DC loads and is divided into two isolated groups, each with eight outputs. The nominal current per output is 2 A; Siemens documents a permissible range of 5 mA to 2.4 A for the signal 1. The nominal load voltage is 24 V DC and may be between 20.4 and 28.8 V DC. For each supply voltage group, the total current is at 20 °C to 4 A and at 60 °C to 2 A. For DC actuators, a maximum lamp load of 10 W and up to 100 Hz switching frequency with ohmic load are specified. For inductive loads, a maximum of 0.2 Hz applies at 1 A or 0.1 Hz at 2 A. The switching delay is at most 1 ms. Electronic short-circuit protection responds in the range from 2.8 to 6 A; the internal limitation of the inductive switch-off voltage is a maximum of -30 V. Green status LEDs show the status channel by channel, even if the front connector is not inserted. The module does not offer any diagnostic or interrupt functions. Unshielded cables may be up to 600 m long, shielded cables up to 1,000 m long. The current requirement from the S7-400 backplane bus is typically 110 mA and a maximum of 160 mA at 5 V DC; a maximum of 30 mA is drawn from the load supply L+ without load. The typical power loss is 5 W. With 25 x 290 x 210 mm and approximately 600 g, the module corresponds to the narrow S7-400 design. For commissioning, each eight-channel group must be supplied with the rated load voltage at least once. When replacing, the complete order number, terminal assignment, group supply and load characteristics must be checked together; the successor 6ES7 422-1BH11-0AA0 must not be treated as equivalent without checking the supply characteristics.

FAQ

Frequently asked questions

Contact us
Which loads can Siemens 6ES7 422-1BH10-0AA0 switch?

The SM 422 provides 16 outputs for 24 V DC with a rated current of 2 A per output. Siemens specifies switching frequencies up to 100 Hz for resistive loads.

How are the outputs of the SM 422 grouped?

The 16 outputs are arranged in two electrically isolated groups of eight channels. Each group must be supplied with the rated load voltage for commissioning.

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.
