| Item | Specification |
|---|---|
| Part Number | 086339‑501 |
| Official Designation | Micro‑101 Sensor Signal Processing Daughter‑Board, high‑performance variant |
| Manufacturer | ABB AccuRay |
| Product Family | MPRC‑HKQCS Paper Machine QCS System |
| Product Type | Plug‑in mixed‑signal sensor processing daughter‑board |
| Installation | Plug‑in daughter‑board, inserts into dedicated slot of 086345‑004 ASPCBP main control backplane inside MPRC controller rack |
| Power Supply | 5 VDC bus power fed from rack backplane, no standalone external power connector |
| Lifecycle Status | Obsolete / End‑of‑Life. Original OEM manufacturing is fully discontinued. Only new‑old‑stock, refurbished and field‑pulled used maintenance spare parts are available; no brand‑new factory production units can be ordered. |
| ESD Handling Requirement | High‑sensitivity mixed‑signal PCB populated with precision analog amplifiers and FPGA chips. Anti‑static wrist strap and anti‑static mat are mandatory during installation, replacement and inspection operations. |
| Variant Note | 086339‑501 is the upgraded high‑performance revision of base‑model 086339‑001, featuring improved analog signal noise suppression, wider sensor input dynamic range and optimized firmware logic for heavy‑disturbance paper‑mill field environment. Direct drop‑in physical compatibility exists, but MPRC main controller firmware revision must match before replacement to avoid measurement offset or channel fault alarms. |
Electrical & Interface Specifications
- Backplane Interface: Multi‑pin gold‑plated edge connector, connects to ASPCBP internal parallel system bus for power supply, address bus, data bus, control strobe signals and system ground reference.
- Sensor Input Interface: On‑board signal conditioning circuits for low‑level weak analog measurement signals transmitted from QCS scanning‑head Micro‑101 sensor assembly.
- Signal Type: Micro‑volt‑level raw analog sensor signals, reference compensation signals, channel diagnostic feedback signals.
- On‑Board Circuitry: High‑precision instrumentation amplifiers, anti‑aliasing analog filter networks, multi‑channel high‑resolution ADC, programmable FPGA for real‑time data pre‑processing, isolated diagnostic monitoring circuits.
- Power Consumption: Typical 6.5‑8.5 W under full‑load working condition.
- Operation Limitation: Cannot operate as standalone hardware. Must be deployed inside complete MPRC‑HKQCS rack system including main CPU unit, 086345‑004 backplane, SRAM memory daughter‑boards and related auxiliary modules.
- Compatibility Matrix
- Compatible Backplane: 086345‑004 ASPCBP Main Control Backplane
- Cooperates with: 086318‑002 / 086318‑501 SRAM memory daughter‑boards, 086329‑004 ECS end‑column sensor board
- Slot Constraint: Must occupy designated Micro‑101 dedicated slot position; random slot migration will trigger hardware initialization failure and sensor channel offline alarms.
- Difference from base version 086339‑001: Enhanced EMI filtering circuit, extended input signal dynamic range, optimized temperature drift compensation algorithm, conformal‑coating formulation upgraded for higher resistance against paper‑mill corrosive vapour.

Main Functions
- High‑performance Micro‑101 sensor signal processing daughter‑board for legacy ABB MPRC‑HKQCS paper‑machine quality control system. It undertakes acquisition, conditioning, filtering and digital conversion for weak raw measurement signals output by scanning‑head quality sensor.
- Receives micro‑volt‑level analog measurement signals from field‑mounted Micro‑101 sensor assembly. Executes multi‑stage amplification, noise filtering, temperature‑drift compensation and analog‑to‑digital conversion, converts raw physical signals into calibrated digital data which is transmitted to MPRC main CPU via backplane parallel bus.
- Provides continuous real‑time channel self‑diagnosis function. It monitors input signal amplitude range, circuit bias state and sensor loop health status; reports open‑circuit fault, short‑circuit fault, signal over‑range abnormality and internal board hardware failure to main controller, and outputs corresponding fault alarm codes on system HMI for field maintenance guidance.
- Delivers high‑quality pre‑processed measurement data for paper‑web quality index calculation, including basis weight, moisture, thickness and other critical paper‑making parameters. The upgraded circuit design of 086339‑501 effectively suppresses electromagnetic interference interference generated by paper‑mill on‑site frequency‑conversion equipment, reduces measurement jitter and data fluctuation.
- Typical field failure symptoms
- Unstable and jittery quality measurement readings, large data drift during cabinet temperature variation
- MPRC controller reports Micro‑101 channel hardware fault, sensor signal over‑range alarm
- Partial or complete loss of quality measurement data from scanning head
- Intermittent measurement abnormality triggered by cabinet vibration
- Common root causes: aging of on‑board precision analog components, gold‑plated edge‑connector contact oxidation, conformal‑coating damage caused by dust contamination, sensor wiring degradation reflected to board‑level diagnosis.
- Purely maintenance‑oriented spare‑part component. It is only used for repair and replacement of existing legacy paper‑mill QCS installations, and is not applicable for new‑project engineering construction.
Typical Applications
- Spare‑part replacement for Micro‑101 sensor signal processing daughter‑board inside ABB MPRC‑HKQCS QCS control rack.
- On‑site troubleshooting scenarios: severe measurement data jitter, sensor channel fault alarms, unstable quality index output caused by strong on‑site EMI interference, aging of original 086339‑001 base‑version board.
- Preventive‑maintenance spare‑part inventory preparation for legacy paper‑mill QCS control cabinets, especially for paper‑making sites with high‑corrosion and high‑EMI environment.
- Hardware refurbishment and performance upgrade for decommissioned MPRC‑HKQCS controller assemblies.
