          PRODUCT DESCRIPTION

          Sixteen relay outputs for separately referenced switching circuits

          Siemens 6ES7288-2QR16-0AA0 is the EM QR16 relay-output expansion module for S7-200 SMART. It provides sixteen dry-contact outputs for documented AC or DC switching ranges, with a maximum 2 A per point and no digital input channels.

          Four output isolation groups follow the actual common-terminal allocation, not four identical four-channel blocks. Configurable last-value or substitute-value behavior governs STOP operation, while relay loading, contact life and external suppression remain important checks because internal overload protection is not provided.

          RELAY OUTPUT EXPANSION

          Plan relay contact loading independently from module logic power

          The QR16 adds sixteen relay dry contacts without adding digital input channels. Its relay interface allows AC or DC switching within the specified ranges, but the load supply, relay-coil supply and CPU logic power serve different purposes. Review the full station power plan without treating contact current as module bus consumption.
          Use the QR16 diagram and common-terminal table to allocate circuits across the four output isolation groups. Contact inrush, lamp loading and inductive switching need separate attention from the steady 2 A point rating. The original documentation specifies no overload protection and does not support assuming that all output terminals share one common.
          Relay behavior must also be matched in software and maintenance planning. Preserve the intended STOP value, allow for the documented switching delay, and apply suitable load suppression. Historical Siemens sources disagree on some supply-current and common-loading values; those disputed figures require an applicability check rather than an averaged or blended specification.

          Features:

          • Dry contacts and separate power roles
          • Four documented output groups
          • Contact wear and load suppression
          The Siemens 6ES7288-2QR16-0AA0 requires the documented hardware configuration, installation conditions and interface arrangement to be verified before system integration and commissioning.
          INTERCHANGEABILITY

          Verify the complete replacement identity before commissioning

          Read the full 6ES7288-2QR16-0AA0 code on the installed item. Do not choose by a short DR16 label in an older datasheet or by a similar terminal arrangement. Preserve the station position and configuration so that output addresses remain consistent with the existing program.
          Before reconnecting loads, compare the original QR16 pin assignments, common groups and the field voltages. Review external fuses, contact inrush and suppression for inductive circuits. A relay having the same nominal 2 A point rating does not by itself establish matching connection groups, insulation or switching performance.
          Power must be removed from the CPU and associated equipment before replacement. The replacement inspection should consider contact history and actual unit condition separately from the manufacturer design-life figures. Reconfirm STOP behavior and the application commissioning procedure after the correct module has been secured and connected.

          Features:

          • Full QR16 article verification
          • Field voltage and suppression review
          • Condition separate from design life
          The Siemens 6ES7288-2QR16-0AA0 requires replacement verification based on its complete order number, installed hardware, signal configuration and project documentation.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about 6ES7288-2QR16-0AA0

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • Is EM QR16 the same product as EM DR16?

            No. The exact QR16 order code identifies a 16-output relay module in the system manual. DR16 identifies a combined digital input/output module. An older datasheet contains a DR16 label against the QR16 code, so identify this product by its complete order number.

          • Can it switch AC and DC loads?

            Siemens lists relay dry contacts for 5 to 30 V DC or 5 to 250 V AC. Each load must still be checked against the contact rating, inrush, common loading and application protection.

          • Are sixteen relay contacts equivalent to sixteen transistor outputs?

            No. QR16 uses mechanical relay contacts with a maximum 10 ms switching delay and specified cycle life. The QT16 transistor module has a different output circuit and is not an automatic substitute.

          • How are the output commons organized?

            The four groups contain six, two, two and six outputs. Follow the exact QR16 drawing and connector Table A-84 for the common-terminal allocation; the groups are not four identical four-output blocks.

          • Is external protection or suppression needed?

            The table specifies no overload protection. Siemens also requires suitable suppression for inductive loads and highlights the correct placement of external resistor/capacitor suppression when relay modules switch AC inductive loads.

          • Does the cycle-life figure prove the condition of a used unit?

            No. The manual gives design reference values of ten million no-load mechanical operations and one hundred thousand operations at rated load. These do not show the actual contact history or remaining life of an offered module.

          • Why are power-current and group-current values omitted here?

            The 2020 datasheet and V2.8 manual list different supply-current and common-loading figures. Match those ratings to the documentation applicable to your module's hardware before sizing power supplies or load groups; the differing figures are not interchangeable.
