Cable selection: the original page and its V2.1.2 download state extension to 100 m. The later V2.2.1 document changes the cable description to a 25 m replacement option. Confirm the supplied sensor revision and supported cable assembly before planning a long run; do not apply the older extension limit to every unit.
Using the sensor in an LED display system
Include the multifunction-card model, required cable length and installation location when requesting a quotation. If replacing an existing sensor, provide its label and connector details so the replacement can be checked against the existing wiring. The sensor’s IP65 rating does not establish the protection rating of the complete control cabinet or cable connections.

Frequently asked questions
What does the NovaStar MTH310 measure?
It measures ambient temperature. In a compatible LED control system, the reading can be shown on the LED display.
Which function card connects to the MTH310?
The documented connection is to the NovaStar MFN300 multifunction card. Confirm the card and wiring arrangement before ordering a replacement sensor.
Can I extend the MTH310 cable to 100 meters?
The original V2.1.2 document states that limit, but V2.2.1 specifies a 25-meter replacement cable instead. Ask sales to confirm the supported cable length for the actual revision supplied.
Does the sensor need a separate power supply?
No separate external power supply is required in the documented connection. Follow the multifunction-card wiring instructions.
What is the sensor’s measurement range?
The specified measurement range is −20°C to +75°C. This is the temperature-measurement range, not a statement about every component in the display system.
