Product description

ABB DX910B is a configurable S900 digital module for mixed input and output tasks rather than a fixed standard DI or DO module. ABB identifies DX910B as Digital Input or Output DIO8-B for S900 I/O type B. The module is suitable for installation in Zone 2 and for intrinsically safe field devices located in Zone 2, Zone 1 or Zone 0. Its 8 I/O channels can be configured as a mix of inputs and outputs. ABB specifies dry contacts or NAMUR proximity switches on the input side and low-power intrinsically safe valves on the output side. This combination supports process applications where discrete signals and small valve outputs share one S900 station. System communication uses PROFIBUS DP. ABB also documents redundant power and communication, Hot Configuration in Run, Hot Swap, advanced diagnostics, FDT/DTM configuration, G3 coating and automatic diagnostics. Short-circuit and wire-break detection, electrical isolation between input and bus and between input and power, and a common return conductor for inputs and outputs are further technical characteristics. DX910B measures 104 x 20 x 104 mm and weighs 0.125 kg. Replacement selection must consider the complete part number, type B hazardous-area version, NAMUR or dry-contact inputs, valve-output function and mixed I/O configuration. These points ensure that the existing S900 wiring, S900 hazardous-area concept and diagnostic behaviour remain compatible.

FAQ

Frequently asked questions

Contact us
Is there a warranty?

Yes. We provide a 14-day functional warranty for used items. The component must be functional on arrival, and the warranty applies only while the warranty seal remains undamaged. 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.

How quickly do you ship, and which shipping options are available?

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.

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.
