Transmitted signals encompass process variables collected from 4-20 mA HART loop protocol instruments and field sensors connected to remote I\/O sub-assemblies. Operating over a 10 Mbps RIO bus layer, the interface manages hardware polling cycles and packet framing across DB-37 multi-conductor cables while maintaining signal integrity across industrial noise profiles.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How many field I\/O devices can be connected to a single RB301 master card segment?\u003c\/p\u003e\n\u003cp\u003eA: A single RB301 master card segment supports up to 31 Yokogawa RIO bus field devices connected in a daisy-chain or drop topology.\u003c\/p\u003e\n\u003cp\u003eQ: What host expansion slot is required to install the RB301 card?\u003c\/p\u003e\n\u003cp\u003eA: The card requires a standard half-length PCI expansion slot on the host computer or Human Interface Station (HIS) backplane.\u003c\/p\u003e\n\u003cp\u003eQ: What is the transmission speed of the DB-37 RIO bus interface?\u003c\/p\u003e\n\u003cp\u003eA: The RB301 operates at a fixed bus communication speed of 10 Mbps over the DB-37 connector interface.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003ePower down the host workstation and disconnect the main AC supply before installing or removing the RB301 PCI card. Observe strict electrostatic discharge (ESD) procedures, wearing a grounded wrist strap when handling the printed circuit board. Insert the card securely into a vacant PCI slot on the motherboard and fasten the bracket mounting screw to ensure frame ground continuity. Connect the DB-37 cable assembly, locking the thumb screws firmly. Ensure shielded twisted-pair cables are grounded at a single earth ground point to prevent ground loop currents from interfering with 10 Mbps signal transmission.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":53278222352693,"sku":"RB301","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/RB301_846892b9-f1c2-41ff-a0cd-87c3354a7e2b.jpg?v=1786607826","url":"https:\/\/www.5gplc.com\/products\/yokogawa-rb301-rio-bus-interface-master-card","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
