This module is ABB DCS AC800 series industrial control spare module, produced in accordance with IEC industrial standards and ABB factory specification requirements. It is rack plug-in type automation component applied for process signal acquisition and bus data transmission in distributed control system of process industry.

3BDZ is fixed internal part number prefix for ABB AC800 series control spare parts.000398 is exclusive catalog serial number of this module.R1 stands for first official revised hardware version of this component.

Rated operating power is standard industrial DC supply. Operating ambient temperature ranges from -25℃ to +60℃, storage temperature ranges from -40℃ to +85℃, protection class IP20 for cabinet installation. The product passes IEC61000 EMC anti-interference and industrial vibration certification.

Rear golden finger connector inserts into system rack backplane to realize power input and internal control bus communication. Front terminal interface is used for field instrument signal wiring. No independent built-in Ethernet or separated serial communication port on module front side.

It collects digital or analog field signals from on-site transmitters and sensors, completes internal signal filtering and conversion, uploads processed valid data to main controller via rack backplane bus. Meanwhile it receives downlink control commands from master unit to output driving signals for field actuators and realizes partial site interlock control.

It is widely equipped inside DCS cabinets of thermal power, petrochemical, metallurgy, cement and papermaking large-scale process automation projects as key replacement spare part.

Cut off rack power before plugging and replacement, insert module into specified rack slot and lock fixing fastener. Complete field wiring strictly in accordance with terminal specification. Implement regular maintenance every six months, clean dust on module casing and connector with dry soft brush and avoid any liquid detergent. Replace full module if continuous signal abnormality or bus communication fault exists after troubleshooting external wiring, unauthorized disassembly and internal circuit modification are forbidden.
