ABB DSTS104 Serial Communication Interface Board

Technical Specifications Model: DSTS104 System Compatibility: ABB Advant Master DCS System Communication Port Quantity: 4 serial ports Interface Standard: RS232 / RS485 configurable Mounting: Eurocard controller rack plug‑in Power Supply: From controller rack backplane Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE

Functional Features Four independent configurable serial communication ports support RS232 and RS485 interface standards. Realizes serial data exchange between Advant Master DCS and third‑party instruments and subsystems. Built‑in communication signal isolation restrains external equipment interference from invading controller rack. Front‑panel LED indicators display port sending, receiving and board fault status. On‑board self‑diagnosis function monitors power supply and communication hardware fault. Supports hot‑swap operation under authorized Advant Master maintenance workflow.

Application Scenarios DSTS104 serial communication board spare‑part replacement for Advant Master controller rack. Serial‑protocol data interconnection between legacy DCS system and third‑party instruments and auxiliary systems. Industrial automation projects requiring multi‑channel serial external device access.

Installation Requirements Insert DSTS104 fully into target controller rack slot and tighten front locking screw. Connect external serial communication shielded cables to front screw terminals, tighten terminals to specified torque. Select corresponding RS232 or RS485 working mode through system configuration software. Implement protective earthing complying with Advant Master system grounding specification. Serial communication cables shall be separated from high‑power power cables inside cabinet. Reserve ventilation heat‑dissipation space around board slot. Ambient operating temperature shall keep within 0 ℃ ~ +60 ℃ without condensation.
