Product description
Siemens 6ES7441-2AA03-0AE0 is the CP 441-2 communication module for the SIMATIC S7-400 controller family. The module has two variable serial interfaces and point-to-point communication is documented. Siemens lists 20 mA TTY, RS 232C and RS 422/485 as interface types. Maximum transmission rate is 115.2 kbit/s. The documented serial protocols and functions include ASCII, 3964(R), RK512 and printer connection. Eight connections are stated in total. Configuration uses STEP 7 with dedicated parameter-assignment forms. Without an installed interface module, maximum current consumption from the backplane bus at five volts is 700 mA. Parameter storage requires 1 to 5 KB per interface; message-text storage is stated as 0 to 55 KB per interface. For a shielded RS-232 cable, the product data sheet lists a maximum length of 10 m. With RS 422/485, a maximum of 1,200 m is documented for shielded cable. The communication module is 25 mm wide, 290 mm high and 210 mm deep. Complete overall dimensions are therefore 25 × 290 × 210 mm in the order width, height and depth. Module width is 25 mm and matches the documented mechanical version of this type. Siemens states an approximate module weight of 720 g; a separate interface module is listed at approximately 100 g. The visible weight value describes the CP-441-2 module. Dimensions and weight refer to the individual module, not transport packaging or a complete populated rack. Product family, order number, channel count, interface types, transmission rate and mechanical data identify version 6ES7441-2AA03-0AE0.
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

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.
