Configured for switching physical isolation loops, the hardware routes up to 8 relay outputs operating over mixed electrical potentials. It handles cyclic load processing between host automation logic configurations and external execution points, maintaining a galvanic threshold via integrated structural relays under an explicit internal voltage source.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eDO571 1TNE968902R2202\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.138 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e135 mm x 74 mm x 34 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e4.5 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Digital Outputs\u003c\/td\u003e\n\u003ctd\u003e8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eRelay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage Type\u003c\/td\u003e\n\u003ctd\u003eAC \/ DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e24 to 230 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage Maximum\u003c\/td\u003e\n\u003ctd\u003e195.5 to 276 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current\u003c\/td\u003e\n\u003ctd\u003e2 A per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Type\u003c\/td\u003e\n\u003ctd\u003ePluggable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDegree of Protection\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e20.4 to 28.8 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication Velocity Licences and I\/O Density Scaling\u003c\/h3\u003e\n\u003cp\u003eThe internal logic card architecture maps the 8 mechanical contact arrays to independent bit registers within the host PLC chassis. When configuring extensive local nodes demanding high-speed synchronization, system engineering must match module placement profiles with active backplane bus communication velocity licences to maintain fixed scan cycle integrity. This optimization allows flexible I\/O density scaling across adjacent eCo-series frames without introducing tracking register propagation delays or disrupting deterministic processing schedules during high-frequency relay state transitions.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the physical constraints and electrical hazards of hot-swapping the DO571 module?\u003c\/p\u003e\n\u003cp\u003eA: This module does not support live hot-swapping functionality. The primary 20.4 to 28.8 V DC supply lines and all external loop loads up to 240 V AC must be fully isolated before extracting the pluggable terminal blocks to prevent contact arcing, logic errors, or permanent circuit board component degradation.\u003c\/p\u003e\n\u003cp\u003eQ: How does the module react if the external switching voltage reaches the maximum 276 V limit?\u003c\/p\u003e\n\u003cp\u003eA: The module accommodates transient peaks up to 276 V across the open relay poles. Continuous exposure to voltages above this threshold compromises internal trace insulation paths and can induce premature contact welding or dielectric degradation across adjacent channels.\u003c\/p\u003e\n\u003cp\u003eQ: Are the 8 relay channels sharing a single common line or are they isolated from each other?\u003c\/p\u003e\n\u003cp\u003eA: The technical matrix demands referencing the wiring diagrams for grouped commons. Exceeding the combined 2 A current distribution limit per block can trace thermal faults onto the pluggable connection interface.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the 0.138 kg assembly onto a standard symmetrical DIN rail secured within an IP20-rated, ventilated industrial panel structure. Ensure that the DIN rail framework is directly bonded to the primary station copper earth bar using a low-impedance connection path to mitigate noise induction. Route all high-voltage inductive output lines (up to 240 V AC) through distinct wireways separated from low-voltage DC communication bus cables to suppress magnetic cross-talk. Maintain standard air spacing above and below the 135 mm x 74 mm x 34 mm housing boundaries to facilitate heat dissipation within the bounded 0 to +60 deg C operational threshold.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53054215979317,"sku":"DO571 1TNE968902R2202","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/DO5711TNE968902R2202.png?v=1782893624","url":"https:\/\/www.5gplc.com\/products\/abb-do571-1tne968902r2202-distributed-automation-i-os","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
