ABB DSTS104

Product Brief:​ The DSTS104 acquires binary ON/OFF status from dry contacts or 24 V DC (or 48/110/230 V per version) field devices and presents them to the S100 controller’s I/O image. It is a plug-in module for the S100rack, addressed automatically by the controller via the DSTK150 bus coupler.

Description

ABB DSTS104

  • Technical Specifications (typical 24 V DC version):
    • Input Channels: 16 (single group) or 32 (2 groups × 16)
    • Input Voltage: 24 V DC (18–30 V); threshold ON ≥11 V, OFF ≤5 V; other voltage grades available (48 V DC, 110 V DC, 230 V AC 50/60 Hz)
    • Input Current: ≈7 mA @ 24 V DC per channel
    • Response Time: <10 ms (typical); software filter 0–63 ms
    • Isolation: Group-to-backplane 500 V DC; channel-to-channel within group common 0 V
    • Power: From S100 backplane (5 V logic)
    • Indicators: Module Run / Error LED; some versions have group status LED
    • Operating Temp.: 0 °C to +60 °C
    • Mounting: S100 I/O rack slot
    • Certifications: CE, UL
  • Functional Features / Application / Structure / Working Principle / Installation / Precautions:
    • Same principles as DSSB140 — wire field device between input terminal and common (0 V for sinking, +24 V for sourcing depending on config)
    • For 110 V DC / 230 V AC versions: verify correct module label before wiring — applying wrong voltage destroys module
    • Use shielded cable for long runs in noisy environments; ground shield at one end
    • In controller configuration software assign starting address; verify channel mapping in online diagnostic view
