I. Product Ownership

Swedish original factory product, compatible with ABB Advant Master / AC800M / System800xA DCS systems. The internal signal aggregation board within the system is used for centralized collection of on-site dispersed analog + discrete signals, as well as protocol aggregation and transfer.

Core Function

Multiple scattered on-site instrument signals (AI/DI) are connected to this card through the terminal board. After signal conditioning and isolation within the board, they are uniformly uploaded to the main control CPU through the backplane bus, simplifying cabinet wiring and reducing line interference.

Power Supply: Backplane 24VDC bus power supply, no need for external power supply. CPCI European card structure, rack slot installation

Hardware Architecture: 32-bit RISC processor + 2MB onboard cache, built-in signal isolation, overvoltage and surge protection circuits Interface configuration

Dual heavy-duty connectors: 115-pin + 135-pin, with external I/O terminal base

Built-in RS485 bus interface, supporting Modbus RTU/HART instrument protocols compatibility

Physical dimensions & weight: standard Eurocard card; net weight ≈ 0.5kg

Environment: operating temperature 0℃～+55℃, IP20, installation in industrial cabinets, does not support hot-swappable replacement

Channel capacity: integrated multi-channel signal aggregation, compatible with analog 4-20mA / thermocouple + 24VDC switch quantity mixed acquisition

Product Features

Signal centralized filtering: unified noise reduction and isolation for multiple on-site signals, suitable for strong electromagnetic conditions in power plants / chemical industries

Fault self-diagnosis: panel LED status lights, single-channel open circuit, short circuit, communication abnormality indicator alarms

System expansion: multiple PFSK152 boards can be paralleled in the same chassis for expansion, sharing the load of full plant instrument signal acquisition

Firmware online upgrade: through 800xA Control Builder for remote program flashing, no need to disassemble the machine

Application Scenarios

Thermal power / hydropower plants: centralized collection of boiler measurement points, turbine temperature and pressure instrument signals

Petrochemical industry: local transmitters and valve positioners of refining and chemical plants aggregated into DCS

Metallurgy and papermaking: remote I/O signal aggregation of production line instruments, replacement of old Advant system spare parts
