Vutlan VT490 Humidity and Temperature Sensor (CAN)

Vutlan VT490 — CAN Humidity and Temperature Sensor

High-accuracy temperature and humidity sensor that daisy-chains over CAN bus. Connected in series on a single cable for multi-point measurement at rack fronts/backs, hot/cold aisles or around a room. Each parameter is a separate element in the web interface; dew point is calculated in the interface.

Key features

  • Temperature accuracy ±0.4 °C (−10…+85 °C), resolution 0.1 °C.
  • Relative humidity accuracy ±3% RH (0–80% RH).
  • CAN (CANopen) digital sensor — 2 × RJ11 6P4C ports, daisy chain.
  • Max 225 m from the master; 24 devices recommended per CAN line, an extra CAN-12V-1A supply per 12 devices.
  • Temperature and humidity are separate elements — individual thresholds and notifications; dew point calculated.
  • Operating −40…+100 °C, 0–95% RH; 12V DC, 1 W.
  • TR switch (last device on the line) and RUN/ERR LEDs; desktop or wall mounting.
  • 68 × 47 × 26 mm; compatible masters: VT225t, VT335G, VT336t, VT825G, VT855G, VT604G/VT608G, VT-PDU, LR800.
  • Promark: hot/cold aisle measurement-point plan and CAN chain design.

Typical applications

01

Rack front (cold) and rear (hot) measurement — many racks on one CAN chain.

02

Hot/cold aisle balance and cooling-efficiency tracking.

03

Server room, UPS and battery room climate monitoring.

04

Humidity-sensitive spaces such as warehouses, archives and greenhouses.
