ABB 3BHE021083R0101 XVC770BE101 – Digital Output Module | AC800M DCS Platform
Engineering Background
The ABB XVC770BE101 (part number 3BHE021083R0101) is a high-density digital output module engineered for ABB’s AC800M distributed control system — one of the most widely deployed DCS platforms in power generation, pulp & paper, oil & gas, and heavy process industries. Designed to ABB’s Advant/800xA architecture standards, this module delivers deterministic, galvanically isolated digital switching with the reliability demanded by continuous-process environments.
Product Positioning
Konmask.com supplies this module as verified surplus and new-surplus stock, providing procurement engineers with a cost-effective, lead-time-free alternative to OEM factory orders — without compromising on traceability or functional integrity.

Engineering Advantages
- Galvanic Isolation — protects controller backplane from field-side transients and ground loops
- Hot-swap Compatible — supports online module replacement within AC800M redundant configurations
- Deterministic Scan Cycle — synchronized with AC800M controller for predictable I/O response
- Compact Form Factor — high channel density minimizes cabinet footprint
- Long Service Life — ABB industrial-grade components rated for continuous 24/7 operation
- Backward Compatible — integrates with existing 800xA and Advant OCS configurations without firmware changes
System Architecture & Signal Flow
The XVC770BE101 resides in the AC800M I/O rack and communicates with the PM8xx controller via the internal S100 I/O bus. Field-side digital output signals are driven through optocoupler-isolated output drivers, switching external loads (solenoids, relays, indicator lamps, VFD enable signals) in response to controller logic. The module’s status LEDs provide local diagnostics for each channel, and fault states are reported back to the 800xA operator station via the controller’s diagnostic channel — enabling predictive maintenance without physical inspection.
Sourcing & Quality Verification
- All units sourced from decommissioned plant upgrades or authorized distributor overstock
- Visual inspection: connector pins, housing integrity, label legibility
- Functional bench test: output channel actuation verified under rated load
- Anti-static packaging with desiccant for long-term storage integrity
- Traceability documentation available on request (decommission records, test reports)
- 30-day return window for DOA units; 90-day functional warranty on tested stock
Procurement Process
- Confirm compatibility — provide your AC800M controller model (PM861, PM864, PM866, etc.) and 800xA version
- Request stock status — contact support@konmask.com for real-time availability and lead time
- Submit PO or inquiry — include quantity, required condition (new surplus / tested), and delivery address
- Receive shipping confirmation — EXW Xiamen; DDP available for select destinations
- Incoming inspection — use provided test report as acceptance baseline
Technical FAQ
Q: Is 3BHE021083R0101 the same as XVC770BE101?
A: Yes — 3BHE021083R0101 is ABB’s full catalog part number; XVC770BE101 is the module type designation printed on the housing label. Both refer to the identical hardware.
Q: Which AC800M controllers is this module compatible with?
A: The XVC770BE101 is compatible with the AC800M controller family including PM861A, PM864A, PM866A, and PM891 when used with the appropriate S100 I/O bus configuration. Verify your 800xA software version supports the module’s firmware revision.
Q: Can this module be used in SIL-rated safety loops?
A: The standard XVC770BE101 is not SIL-certified. For safety instrumented systems, ABB’s dedicated SIL-rated I/O modules (e.g., SM811F series) are required. Contact us if you need SIL-compliant alternatives.
Q: What is the typical lead time?
A: In-stock units ship within 3–5 business days. For large quantities or specific condition requirements, allow 7–14 business days for sourcing and testing.
Q: Do you provide export documentation for cross-border shipments?
A: Yes — commercial invoice, packing list, and certificate of origin are standard. HS Code 8537.10 applies. ECCN classification and end-user statements available on request.
