Product description

Siemens 6ES7 400-2JA10-0AA0 is a robust, lightweight aluminum UR2-H rack for the SIMATIC S7-400 automation system. The rack type is designed for central and distributed stations and provides a total of 18 slots in two separate segments with nine slots each. The communication bus and P-bus are routed separately between the two segments. This enables a redundant S7-400H configuration with two system halves located directly next to each other on one common rack, provided that the configured CPU, power-supply, and module assignment match. Siemens specifies a width of 482.5 mm, a height of 290 mm, and a depth of 27.5 mm. The aluminum rack weighs approximately 3 kg. An ambient temperature range from 0 to 60 °C is specified for operation; storage and transportation permit 0 to 70 °C. The rack provides one communication bus and one P-bus, each segmented. In addition to the complete order number, the UR2-H design, the two sets of nine slots, the position of both segments, and the mechanical installation dimensions are decisive. For spare-parts procurement, it should also be checked whether the existing plant uses the aluminum variant 6ES7 400-2JA10-0AA0 or the heavier version 6ES7 400-2JA00-0AA0. Both variants share central system characteristics but differ in material and weight. Before installation, the mounting space, grounding, rack fastening, slot assignment, power supplies, CPU pairing, and existing STEP-7 hardware configuration must be compared. The rack itself does not replace an interface, CPU, or power-supply module; it forms the mechanical and electrical basis of the configured S7-400H station.

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.
