Planning the monitoring connection
Match the receiving system to the sensor voltage, RS485 wiring and MODBUS RTU settings. Assign communication addresses and select a supported baud rate for the bus. The listed 1,200 m communication distance is distinct from the supplied 5 m wire length.
The measurement range describes what the sensor measures; it is not a separate enclosure operating-temperature or weatherproof rating. The linked specification does not state an IP rating, so confirm the installation protection needed for the intended location.
Frequently asked questions
What does the Colorlight SSR-TEMP measure?
It measures temperature and relative humidity. The specification lists −40°C to +120°C for temperature and 0–100% RH for humidity.
Which interface and protocol does SSR-TEMP use?
It uses RS485 with the MODBUS RTU protocol. Supported addresses are 1–247, with baud rates from 1,200 to 19,200 bit/s as listed in the table.
What power supply does the SSR-TEMP require?
The rated supply is DC 5–12 V. The specification lists average power consumption below 0.1 W.
Is a 1,200 m cable supplied with the sensor?
No. The specification lists communication distance up to 1,200 m, while the standard wire length is 5 m. Plan the bus cabling separately.
Can the SSR-TEMP be mounted outdoors without protection?
The specification lists guide-rail, indoor wall and ceiling mounting but does not provide an IP rating. Confirm suitable protection and installation conditions before using it in an exposed location.
