ABB DSQC322

Product Brief:​ The DSQC322 is a standard DSQC-series I/O board for ABB IRC5 robot controllers. It provides 16 digital inputs (24 V DC, sinking or sourcing configurable in software) and 16 digital outputs (24 V DC, 0.5 A sourcing transistor) via two 25-pin D-sub or screw-terminal adapters (TB) on the robot cabinet’s DSQC651/652 termination unit. It communicates with the IRC5 main computer over the internal DeviceNet-based DSQC bus and is used to interface grippers, fixtures, safety gates, conveyor sensors, and stack lights with the robot program (RAPID).

Description

ABB DSQC322

  • Technical Specifications:
    • Digital Inputs: 16 channels, 24 V DC (18–30 V), typ. 7 mA/channel; accepts PNP or NPN (wired accordingly)
    • Input Threshold: LOW ≤5 V, HIGH ≥11 V; software filter 0–32 ms
    • Digital Outputs: 16 channels, 24 V DC high-side MOSFET, sourcing (PNP); 0.5 A max/channel, total ≤8 A per module
    • Output Protection: Short-circuit and over-temperature protected, auto-recovery
    • Supply Voltage: 24 V DC ±10 % (from robot controller internal supply or external UP)
    • Power Consumption: Typ. 3 W (loaded)
    • Interface: Connected via DSQC termination board (DSQC652 TB or equivalent) — 50-pin header to D-sub / screw terminal
    • Bus: ABB DSQC internal bus (DeviceNet derivative, auto-addressed by controller)
    • Indicators: Per-channel LEDs (Input green, Output yellow) + module status LED
    • Operating Temp.: 0 °C to +55 °C; Storage –40 °C to +70 °C
    • Humidity: 5–95 % RH non-condensing
    • Mounting: PCB mounts inside IRC5 controller cabinet on dedicated DSQC I/O bracket or in separate I/O box
    • Certifications: CE, UL, cUL, RoHS
  • Functional Features:
    • Direct mapping to RAPID program variables (DI / DO signals)
    • Configurable input debounce filtering per channel group
    • Output freeze / predefined state on communication loss (configurable in IRC5)
    • Hot-swap capable when system configured for it (requires controller FW support)
    • Diagnostic LEDs for rapid troubleshooting without FlexPendant
  • Application Scenarios:
    • Gripper open/close confirmation (input) and actuation (output) on IRB 120 / IRB 2600 / IRB 6640
    • Fixture clamp / part-present sensor monitoring
    • Start / stop command to small 24 V DC conveyors via interposing relay
    • Safety gate monitored input, tower light output
  • Material & Structure:
    • PCB: FR4 with conformal coating option; gold-finger backplane connector
    • Mounting: Metal standoff bracket or plastic guide rail inside IRC5 cabinet
    • External connection via DSQC651/652 termination board (screw or D-sub)
  • Working Principle:

    The DSQC322 is addressed automatically by the IRC5 controller at boot. Digital inputs are read cyclically and placed in the controller’s I/O image; RAPID instructions read these as DI[n]. Output image bits from RAPID (DO[n]) are written to the MOSFET drivers each scan cycle. The module performs self-diagnostics and reports bus errors or output faults to the controller.

  • Installation Requirements:
    • Power down IRC5 controller before installing/removing DSQC board
    • Seat DSQC322 firmly onto the DSQC I/O backplane or termination board header
    • Connect field wiring via DSQC652 termination unit observing PNP (sourcing) or NPN (sinking) convention
    • In RobotStudio / IRC5 configuration, add “DSQC322” to the Unit Type and assign starting signal addresses
    • Reboot controller; verify module Status LED green
  • Precautions:
    • Do NOT exceed 0.5 A per output channel; use interposing relay for solenoid valves >0.5 A coil current
    • Ensure external 24 V DC process supply (if used for outputs) shares 0 V reference with controller 0 V
    • For safety-related signals (E-Stop, guard monitoring), use dedicated safety interface — DSQC322 is standard (non-safety) I/O
    • Handle by PCB edges; use ESD wrist strap when installing
