Description

The Mitsubishi QY41P​ is a 32-point DC digital output module​ for the Mitsubishi MELSEC-Q Series PLC. It uses NPN transistor (Sink type)​ outputs to switch 12/24 V DC loads​ at 0.1 A per point (2.0 A per common group)​ — ideal for driving indicator lamps, small DC solenoid valves, and interposing relay coils.
  • QY41P​ → 32 points, Transistor NPN (Sink), 12/24 V DC, 0.1 A/pt — single-width Q-module (27.4 mm)
  • Contrast: QY42P​ = 64 pt same type; QY82P​ = 64 pt PNP(Source); QY10​ = 16 pt Relay NO.
The module auto-assigns Y-addresses in GX Works2 / GX Developer​ based on slot position (or manually set in I/O Parameters). Each output is optically isolated from the Q-bus.

Key Features

  • Outputs: 32 × NPN Transistor (Sink) — ON = output pulls to 0V through COM terminal
  • Load Voltage: 12–24 V DC (range 10.2–28.8 V DC)
  • Current Rating: 0.1 A / point; 2.0 A / common group (16 pts per COM — QY41P typically has 2 COM terminals: COM0 for Y0–Y17, COM1 for Y20–Y37 in octal)
  • Response Time: ≤ 0.2 ms (ON), ≤ 0.3 ms (OFF)
  • Isolation: Photocoupler between outputs & Q-bus backplane
  • Diagnostics: Module RDY/ERR LEDs; watchdog supervision
  • Country of Origin: Japan (Mitsubishi Electric)

⚠️ Critical Notes:
  1. Sink (NPN) Wiring: QY41P = NPN Sink — Load connected between +24V and output Y□; COM terminals connect to 0V (GND). When ON, Y□ goes to ~0V, current flows through load. If your system uses PNP (load between Y□ and 0V, module sources +24V) → order QY81P (PNP/Source).
  2. COM Terminals: QY41P has 2 COM terminals — COM0 (Y0–Y17 in octal = Y00–Y17 decimal grouping), COM1 (Y20–Y37). Both MUST be tied to 0V for NPN operation. Do NOT apply +24V to COM on QY41P (that’s for PNP module QY81P).
  3. Current Limits: 0.1A/point; 2.0A max per COM group (16 pts). For larger loads use interposing relay or relay-output module (QY10 etc.).
  4. Inductive Loads: Always parallel DC solenoid/relay coil with a flyback diode​ (cathode to +24V side) to protect transistors — module has internal surge diode but external diode recommended for larger coils.
  5. GX Works2 Addressing: 32 points = 2 consecutive device words (Y0000–Y001F hex if start Y0000). Avoid overlap with adjacent slots.

    • COM terminal grouping (2 COMs, 16 pts each — ALL COM to 0V for NPN)
    • Current derating / grouping limit (2A/COM max — load calculation)
    • GX Works2 I/O assignment (start Y addr, 32 pts = 2 words — avoid overlap)
    • Flyback diode recommendation for inductive DC loads
    • Cross-ref to QY81P (PNP 32pt) if wiring mismatch
  • Optional DC PSU sizing consult
