Product description
Documented identifiers and values: 6DD1606-3AC0; IT41; 20; 14; 233; 220 mm; 0.6 kg; 10; 10; 12; 10; 10; 16; 16; 16; 24 V; 50; 15 V; 1 MHz. The analogue outputs also provide a range of -10 V to +10 V, with 16 Bit resolution. With dimensions of 20.14 x 233.4 x 220 mm, a weight of approximately 0.6 kg and +5 V, +15 V and -15 V backplane supplies, Siemens 6DD1606-3AC0 is a clearly defined plug-in spare module for installed SIMADYN D cabinets. The complete Siemens 6DD1606-3AC0 identifier should be retained for replacement records. The differential analogue inputs operate from -10 V to +10 V with 12 Bit resolution. It extends a PM5 or PM6-CPU with combined process signals and occupies one slot in addition to the CPU slot. For fast encoder signals, Siemens specifies up to four 15-V incremental encoders; the source also identifies a second encoder-voltage variant and a track frequency of up to 1 MHz. The binary channels use external 24-V-DC signals. Two 50-pin Sub-D connectors, X6 and X7, connect encoder, analogue and binary signals through suitable SC49, SC54 or SU10-/SB interface modules. The outputs provide a nominal 50 mA and are electronically and thermally protected against short circuits.

Manufacturer / EU responsible person
Which identifier is decisive for Siemens 6DD1606-3AC0?
The full manufacturer and type number 6DD1606-3AC0 is decisive for the order. Selection of the required version and verification for the customer’s installation remain the responsibility of the customer or its qualified personnel and should be based on the manufacturer 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?
