Product description
Siemens 6ES7157-0AC81-0XA0 identifies a SIMATIC DP/PA coupler in the non-Ex version. The module provides the physical connection between PROFIBUS DP and PROFIBUS PA. It converts RS485 transmission on the DP side to the fieldbus physical layer according to IEC 61158-2. Supply voltage is 24 V DC. Siemens documents a fixed transmission rate of 45.45 kBaud for the DP interface, while the PA side operates at 31.25 kBaud. PROFIBUS DP and PROFIBUS PA are electrically isolated from one another. The coupler supplies the connected PA segment and contains the associated bus terminator. Output current for the non-Ex version is specified as 400 mA. The protection rating is IP20. Siemens documentation lists order number 6ES7157-0AC81-0XA0 expressly as a DP/PA coupler for expanded environmental conditions. This is the documented non-Ex execution, and the complete order number is its exact identifier. The Siemens PROFIBUS catalog specifies external dimensions of 40 mm width, 125 mm height and 130 mm depth. The associated product detail specifies a net weight of 503 g. Dimensions and weight refer to the device rather than shipping packaging. The footprint of 40 × 125 × 130 mm documents the required installation space. Order number, non-Ex version, 400 mA output current, the two fixed bus speeds, electrical isolation and IP20 are the decisive identifying characteristics. These details describe the listed 6ES7157-0AC81-0XA0 version and replace the previously approximate weight with the documented 503 g value. Suitability for potentially explosive areas is not asserted for this non-Ex version.
The item supplied will have the stated manufacturer or type number and the stated condition category. Serial number, manufacturing date, labels, colour, packaging and normal signs of use or storage may differ. Specifications
Unless expressly confirmed, technical information is provided to identify the device type. The complete manufacturer or type number is decisive.

What are the external dimensions?
Documented external dimensions are 40 × 125 × 130 mm in width × height × depth order.
What bus speeds are documented?
The DP side operates at 45.45 kBaud and the PA side at 31.25 kBaud.
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.
