Description

## I. Product Overview
Model: CI532V03, Part Number: 3BSE003828R1. It is a dual-bus master communication card for ABB Advant/AC450/AC800M/800xA DCS systems with the third-generation V03 hardware revision. Integrating dual-protocol conversion of AF100 fieldbus master and PROFIBUS-DP CLASS1 master, it enables bidirectional data exchange among three parties: the controller’s MasterBus300 backplane, S800 distributed I/O modules and intelligent DP field devices. As a standard component for auxiliary power DCS systems in thermal and hydropower plants, it connects with DSBC172 S800 base units, REF615/REG670 protection relays, SACO16D1 alarm units and third-party variable frequency drives/PLCs. With CE industrial certification, this slot-mounted card supports hot-swap replacement during system operation.

Naming Definition: CI = Communication Interface card; 532 = model designation for dual AF100 and DP bus; V03 = third-generation optimized hardware; 3BSE003828R1 = unique original manufacturer order code.

II. Electrical Power Specifications
Power Supply: Powered uniformly by DC24V±20% from the MasterBus300 backplane of the controller rack, with no dedicated external power terminals.
Power Consumption: Full-load power consumption per card ≤4.5VA.
Electrical Isolation: Three-port galvanic isolation across the AF100 bus side, DP bus side and system backplane. Bus terminals withstand AC2000V power-frequency voltage to ground for 1 minute, with robust immunity against EMC interference from inverters and protection relays.
Insulation Standard: Compliant with the IEC60255 industrial automation insulation specification.
