It connects to the controller via an 8-pin mini-DIN, the network port uses a second 8-pin mini-DIN, and the Prog\/HMI port uses a 9-pin D-shell connector. The unit requires an external 24 VDC power source rated at 100 mA. Naming and timing details include autobaud on the controller port at 19.2 or 38.4 kbps with automatic CRC or BCC checksum detection, fixed at 19.2 kbps CRC for the controller, the network port supporting DF1 full-duplex at 19.2 kbps with CRC, and the Prog\/HMI port handling 19.2\/38.4 kbps with CRC or BCC in a respond-only role for HMI or programming station connections. The DPS1 ships with a DIN rail mounting bracket and uses standard SLC or MicroLogix programming cables. It is UL and C-UL listed, with CE compliance where applicable. Designed for use across Rockwell Automation serial architectures, the DPS1 accommodates SLC 500, PLC-5, MicroLogix, CompactLogix, and ControlLogix families that rely on RS-232 DF1 serial communication, enabling simultaneous connections to an HMI, a programming station, and a serial network without swapping cables. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657304441134,"sku":null,"price":181.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_40b25b67-9aef-41f5-880a-1f1e018c0d42.jpg?v=1769467723","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-dps1-rs-232-port-splitter","provider":"PLG Automation ","version":"1.0","type":"link"}
