Technical Specifications Back‑plane controller bus interface, multi‑channel RS‑485 serial ports. Auxiliary power 24 V DC, typical power consumption 3.4 W. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Serial channel signal galvanic isolation.
Functional Features Communicates with main controller via back‑plane system bus. Executes serial data packaging and parsing. Collects measurement and status data from external serial intelligent devices. Transmits controller operation commands to connected field equipment. Front‑panel LED indicators show communication link and module fault status. Built‑in hardware self‑diagnosis detects serial link breakage and internal circuit faults.
Application Scenarios Serial communication spare part for ABB Advant DCS control rack. Applied in automation projects needing interconnection with serial‑protocol third‑party equipment.
Performance Parameters Stable serial‑port data transmission performance. Reliable protocol processing capability.
Material Composition Flame‑retardant plastic module housing. Multilayer glass‑fiber epoxy printed circuit board. Serial protocol processing chip and signal isolation assemblies. Back‑plane plug‑in connector and serial signal terminals.
Structural Characteristics Standard rack plug‑in module. Front side fitted with serial communication terminals and status LED indicators. Rear side equipped with back‑plane bus connector. Weight approximately 0.32 kg.
Working Principle After power‑on initialization, module establishes serial data link with external devices. Received field data is processed and transmitted to controller through back‑plane bus. Controller commands are encapsulated into serial frames and sent outward. Diagnosis circuit monitors serial communication link and module hardware operating state continuously.
Installation RequirementsInsert DSTC454 into designated rack slot and lock fixing latch. Connect shielded serial communication cables to front‑end terminals. Ensure back‑plane connector is fully engaged. Restore power supply, configure serial communication parameters and verify bidirectional data exchange.
Usage Notes Use shielded cables for serial signal wiring to reduce interference. Verify data interaction status after module replacement.
