The hardware converts internal system commands into 16 individually isolated relay output signals, driving actuators, solenoid valves, and power contractors without requiring interposing relays. By incorporating individual channel-to-channel galvanic isolation, the unit protects upstream ModuleBus backplane logic against field-side voltage transients, maintains signal separation across alternating current and direct current field loops, and eliminates common-mode ground loops across heavy industrial installation environments.\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\u003eDO828 (3BSE069055R1)\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\u003eSweden\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.18 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e119 mm x 45 mm x 102 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 deg C to +55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e3.5 W (Max field power dissipation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Channels\u003c\/td\u003e\n\u003ctd\u003e16 relay outputs (Normally Open)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e5 VDC to 125 VDC \/ 5 VAC to 250 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Output Current\u003c\/td\u003e\n\u003ctd\u003e2 A continuous per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Isolation\u003c\/td\u003e\n\u003ctd\u003eIndividually isolated, channel-to-channel and to circuit common\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Insulation Voltage\u003c\/td\u003e\n\u003ctd\u003e250 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDielectric Test Voltage\u003c\/td\u003e\n\u003ctd\u003e2000 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Power Draw\u003c\/td\u003e\n\u003ctd\u003e45 mA at +5 VDC ModuleBus \/ 80 mA at +24 VDC ModuleBus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Cable Length\u003c\/td\u003e\n\u003ctd\u003e600 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Terminal Unit\u003c\/td\u003e\n\u003ctd\u003eTU851 \/ TU852 \/ TU854 Module Termination Units\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 and System Diagnostics\u003c\/h3\u003e\n\u003cp\u003eThe DO828 module interfaces directly with the redundant ABB S800 I\/O ModuleBus backplane, maintaining deterministic communication cycle times to ensure real-time command execution. Internal microprocessors supervise the local 12 V power converter supplying the relay coil drives, continuously reporting hardware execution state back to the central controller. Furthermore, the firmware supports full flash compatibility, permitting online firmware updating without physically disrupting adjacent I\/O modules on the same DIN rail segment. Front-panel LED arrays provide immediate visual verification of ModuleBus communication state (Run), module fault conditions (Fault), output status (OSP), and channel-level relay contact actuation.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the DO828 module be hot-swapped while the rest of the S800 I\/O station remains powered?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the DO828 supports live insertion and removal (hot-swapping) when installed on a compatible Module Termination Unit such as the TU851, provided field loop voltages do not exceed safety limits during servicing.\u003c\/p\u003e\n\u003cp\u003eQ: What happens to the 16 relay output channels if backplane ModuleBus communication fails?\u003c\/p\u003e\n\u003cp\u003eA: The module executes its configurable Output State Option (OSP) parameter, immediately driving relay channels to a predetermined fail-safe state (either de-energized open or held at the last valid value).\u003c\/p\u003e\n\u003cp\u003eQ: Does the DO828 require external surge protection for inductive loads?\u003c\/p\u003e\n\u003cp\u003eA: While internal contact rating handles up to 2 A continuous, installing external RC snubber networks across AC inductive solenoids or freewheeling diodes across DC coils extends relay contact life and limits high-frequency transient feedback into the field wiring.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the module by sliding it vertically onto the pre-wired S800 Module Termination Unit (such as the TU851) until the locking latches engage firmly. Ensure that the mechanical keying code matches the terminal unit base to prevent accidental insertion into an incompatible I\/O slot.\u003c\/p\u003e\n\u003cp\u003eRoute all field wiring through dedicated cable ducts, ensuring clear physical separation between sensitive 24 VDC analog sensor cables and the 250 VAC relay load cables connected to the DO828 terminal block. Strip field conductors according to terminal unit specifications, maintaining firm screw torque to avoid thermal hot-spots. Bond all cable shielding to the cabinet grounding bar using low-impedance clamps located immediately at the cable entry point to maximize noise immunity.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":52997550276920,"sku":"DO828 3BSE069055R1","price":188.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/630.1_57ffd05c-1d7a-4b88-b6c6-eb9e29789889.jpg?v=1789883036","url":"https:\/\/www.automodulexpert.com\/products\/abb-3bse069055r1-do828-s800-i-o-digital-output-modules","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
