Product description
Mounted on a DMP terminal block, Siemens 6FX1142-4BA04 is a digital input/output module in the SINUMERIK 800 range. The module comprises 16 inputs and 16 outputs, with galvanic isolation provided for both channel groups. A 24 V supply is specified for the electronics. This voltage is used internally to generate the 5-V logic supply, whose permissible range lies between 4.75 and 5 V. Two indicator lights support immediate electrical assessment: yellow signals that the logic voltage is within tolerance, while red indicates an electronics supply that has fallen below 15 V or a transmission fault. The module also has status indicators for the individual input and output channels. Type coding is set on the associated terminal block through switch positions 1 and 7; this setting cannot be changed on the module itself. On the output side, +24 V and 2 A per output are specified, together with a simultaneity factor of 0.5 per byte. A screw connection mechanically secures the module to the terminal block. With dimensions of 220 × 140 × 40 mm and a weight of 0.70 kg, the unit retains the compact DMP format. The full article identifier distinguishes this galvanically isolated version from earlier variants in the 6FX1142 family. Channel count, coding switches, supply and dimensions are particularly relevant when comparing existing documentation.

What applies if an item develops a defect within 14 days?
For the condition categories “Used, removed from an installation” and “New, old stock”, the contractual 14-day right of return in the event of a defect applies. The defect must occur within 14 calendar days after delivery and be reported in text form within the same period.
In particular, the REHA tamper-evident seal must remain fully intact and our RMA approval is required before return. In an accepted case, we decide between replacement and refund. Details in Section 11 of the Terms.
Which shipping methods and delivery times are available?
The shipping method, shipping cost and estimated delivery time are confirmed for the specific order. Depending on the item, destination and urgency, we can check parcel, express or freight shipping as well as collection.
A delivery date is binding only if we expressly confirm it as binding.
Which payment terms apply?
The payment terms stated in the checkout or order confirmation apply. Depending on the order and customer, payment is made in advance or against invoice.
International deliveries and deliveries to new customers are generally made against advance payment unless we expressly confirm another payment arrangement.
Can I return an item ordered incorrectly or found incompatible?
No. There is no general B2B right of return, exchange, cancellation or withdrawal. Incorrect or duplicate orders and a lack of suitability or compatibility with the customer’s installation are not covered by the contractual 14-day right of return in the event of a defect. Details in Section 12 of the Terms.
Can I request individual pricing for several items?
You may request an individual quotation for several items or larger quantities. We then check availability and pricing for the specific requirement; there is no entitlement to a quantity discount. Open the quick enquiry.
Do you also purchase industrial spare parts?
Yes. You can offer us automation and drive components for purchase. Please provide complete type numbers, quantities, condition details and photographs where possible.
After review, we will tell you whether a purchase is possible and on which terms. Learn more about selling industrial stock.
