Product description

The Heidenhain 260 520 01 is the identification number of the BC 110 B visual display unit for several established TNC contouring controls. In its technical manual, Heidenhain lists the monitor as a hardware component of the TNC 407, TNC 415 B and TNC 425. The display is a 14-inch colour monitor with softkeys and connects by cable to both the logic unit and the TNC keyboard. The BC 110 B therefore provides the visual CNC operator interface, while computing, PLC and axis functions remain in the associated control components. Identification number 260 520 01 denotes the BC-110-B version in which the built-in fan is powered from the visual display unit supply. For this fan, the manual specifies a permissible voltage range of +18 to +28 V at connector X3 and power consumption of 5 W at +24 V DC. Connector X4 is a DC test output only and, according to the manufacturer, must not be connected externally. A test button on the rear supports service diagnostics: when the display unit is powered, it generates a bright rectangular field and helps distinguish a monitor fault from a problem with the PLC graphics board. According to the change history, the BC 110 B has carried this identification number since November 1990. Before replacement, verify the full identification number 260 520 01, installed TNC version, connection cable to the logic unit, keyboard connection, supply, protective earth, connectors and mechanical installation space. The monitor is not a modern TFT replacement and must not be equated with successor models merely because of a similar screen size. Work inside the open unit is subject to the machine's service and safety requirements; commissioning must be performed by qualified CNC service personnel.

FAQ

Frequently asked questions

Contact us
For which controls is the Heidenhain 260 520 01 documented?

Heidenhain lists the BC 110 B visual display unit with identification number 260 520 01 as a hardware component of the TNC 407, TNC 415 B and TNC 425.

What must be checked when replacing the BC 110 B?

Verify the complete identification number, TNC control variant, cable to the logic unit, keyboard connection, supply, protective earth, connectors and installation space. A TFT successor is not automatically electrically or mechanically compatible.

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.
