Allen-Bradley 1747-SN is a Remote I/O (RIO) scanner module for the SLC 500 control platform. Installed in a local 1746 chassis, it acts as the master of an Allen-Bradley RIO link, exchanging discrete I/O and, where supported, block-transfer data with remote adapters and compatible devices. An SLC 5/02 or later processor is required.
The scanner supports a maximum of four logical RIO racks, corresponding to 32 input and 32 output image words. Series B and later units can perform block transfers of up to 64 words per remote device when the application and adapter are configured for that function.

| Product Type | Remote I/O Scanner Module |
| Controller Requirement | SLC 5/02 or later |
| Network Role | RIO master (scanner); remote devices operate as adapters/slaves |
| Discrete Image Capacity | Four logical racks; 32 input and 32 output image words |
| Block Transfer | Up to 64 words per remote device, Series B or later |
| RIO Link Rates | 57.6, 115.2 and 230.4 kbaud |
| Maximum RIO Cable Length (Belden 9463) | 3,048 m at 57.6 kbaud; 1,524 m at 115.2 kbaud; 762 m at 230.4 kbaud |
| RIO Connector | 3-pin scanner connector; Rockwell replacement connector 1746-RT29 |
| Backplane Current Requirement | 600 mA at 5 VDC |
| Operating Temperature | 0 to 60°C (32 to 140°F) |
| Storage Temperature | -40 to 85°C (-40 to 185°F) |
| Relative Humidity | 5–95%, noncondensing |
| Noise Immunity | NEMA ICS 2-230 (per Rockwell installation literature) |
| Historical Agency Markings | UL/C-UL, CE, C-Tick; Class I, Division 2 ratings in Rockwell installation literature. Confirm the markings on the individual unit. |
| Country of Origin | Varies by manufacturing batch; verify unit label. Current Rockwell catalog lists Singapore. |
| Lifecycle Status | Discontinued by Rockwell Automation, effective March 31, 2024 |
The RIO link uses daisy-chained twisted-pair cabling. All participating devices must operate at the same baud rate. The physical cable ends require termination appropriate to the link speed and extended-node setting; shielding is grounded at the scanner end as specified in the installation instructions.
The scanner image and logical rack/group assignments must match the SLC program and the remote adapter configuration. A 1747-SN scanner and a 1747-ASB Remote I/O adapter serve different roles; they are not substitutes.
Rockwell lists an engineering migration path rather than a confirmed plug-in replacement. Any platform migration must be assessed separately from an in-place 1747-SN module change.
