1747-SN | Allen-Bradley RIO Scanner | Long-Range I/O – SLC 500

Allen-Bradley 1747-SN Remote I/O Scanner ModuleExtend your control system over long distances. The 1747-SN scanner module connects your SLC 500 processor to remote I/O devices. It lets you place I/O racks far from the main controller. This saves wiring costs and increases flexibility. The module fits in one chassis slot and is easy to set up.Key FeaturesLong Distance Control: Works over cables up to 10,000 feet long.Fast Data Transfer: Supports two baud rates: 57.6K and 230.4K.Multiple Device Support: Connects up to 16 devices (32 in special mode).Wide Compatibility: Works with SLC 5/02, 5/03, 5/04, 5/05 processors.Easy Setup: Uses simple DIP switches for baud rate selection.Technical SpecificationsBrand: Allen-BradleyModel: 1747-SNSeries: SLC 500Module Type: Remote I/O ScannerCommunication Port: One Remote I/O (3-pin)Baud Rates: 57.6 Kbaud, 230.4 KbaudMax Cable Length: 3048 meters (57.6K), 762 meters (230.4K)Max Devices: 16 normal mode, 32 complementary modeBackplane Power: 600 mA @ 5V DC, 90 mA @ 24V DCOperating Temperature: 0 to 60°CStorage Temperature: -40° to 85°CHumidity: 5 to 95% (non-condensing)Weight: 1 pound (0.45 kg)Cable Type: Belden 9463Termination: 82 Ohm resistor requiredInstallation GuideInstall the 1747-SN in any SLC 500 chassis slot. Use Belden 9463 cable for connections. Set the baud rate using the two DIP switches. Remember to add 82-Ohm resistors at both ends of the network. Always turn off power before module installation.Compatibility InformationControllers: SLC 5/02, 5/03, 5/04, 5/05Network Topology: Daisy-chainSupported Devices: PanelView terminals, PLCs, third-party adaptersWarranty & ShippingWe provide a 12-month warranty on this module.
