By managing I\/O density scaling through redundant power inputs, the unit ensures that backplane bus communication velocity remains stable during primary supply transitions. The unit is engineered to maintain deterministic network conditions, preventing bus-level voltage dips that could interfere with Profinet or EtherNet\/IP deterministic networks during switchover events.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 unit: SS822 Power Voting Unit\u003c\/li\u003e\n\u003cli\u003e1 set: Integrated DIN-rail mounting bracket and connection terminal block\u003c\/li\u003e\n\u003cli\u003e1 unit: Technical instruction documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMechanical Installation and Wiring Protocols\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMounting Guidelines:\n\u003cul\u003e\n\u003cli\u003eInstall the unit on a standard 35 mm DIN rail in a vertical orientation to ensure proper convective cooling.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum 20 mm clearance around the heat dissipation vents of the housing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eWiring Specifications:\n\u003cul\u003e\n\u003cli\u003eConnect dual 24 VDC inputs to the designated redundant supply terminals.\u003c\/li\u003e\n\u003cli\u003eUse cross-sectional cable sizes compatible with the terminal block ratings (0.5 to 2.5 mm squared) to ensure low-impedance connections.\u003c\/li\u003e\n\u003cli\u003eVerify voltage polarity at the inputs before final connection to prevent internal diode reverse-bias.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eQ: How does the SS822 perform power voting?\u003c\/p\u003e\n\u003cp\u003eA: The unit utilizes an internal diode-based OR-ing circuit to select the highest available voltage from two independent 24 VDC sources, ensuring a seamless supply transition.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eQ: Is this unit compatible with non-S800 power supplies?\u003c\/p\u003e\n\u003cp\u003eA: Yes, as long as the connected power supplies provide a regulated 24 VDC output within the tolerance specifications of the S800 system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eQ: Does the SS822 require external fuses?\u003c\/p\u003e\n\u003cp\u003eA: External fusing is recommended on both input supply lines to protect the distribution wiring and the voting unit in the event of a downstream short circuit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eQ: What is the maximum current capacity?\u003c\/p\u003e\n\u003cp\u003eA: The unit is rated for specific continuous current throughput; refer to the technical datasheet for the maximum amperage relative to operating ambient temperature.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eQ: Can I connect more than two power supplies?\u003c\/p\u003e\n\u003cp\u003eA: No, the SS822 is designed specifically for dual-input redundant power voting configurations.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eQ: What indicates an active power supply status?\u003c\/p\u003e\n\u003cp\u003eA: The front panel typically features diagnostic LEDs indicating the presence and health of each independent supply input.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eQ: Is the SS822 hot-swappable?\u003c\/p\u003e\n\u003cp\u003eA: The unit can be removed if the power supplies are de-energized; however, follow site-specific safety protocols for live-work maintenance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eQ: Does the unit affect the backplane bus timing?\u003c\/p\u003e\n\u003cp\u003eA: As a passive power distribution component, it introduces negligible latency, ensuring backplane bus communication velocity remains within operational tolerances.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":46021158469805,"sku":"3BSC610042R1","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/3BSC610042R1_1.jpg?v=1780390879","url":"https:\/\/www.maxwellplc.com\/ga\/products\/ss822-3bsc610042r1-abb-power-voting-unit-s800-i-o","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
