Precautions
■Rated input voltage and range
◆ This instrument (isolator) is powered by 24VDC power supply. It is strictly forbidden to use 220V AC power.
◆ Find the rated input voltage marked on the product and verify that its range matches the following:
◆ Power supply voltage range: 20~30VDC.
◆ Rated power supply voltage: 24VDC
◆ Maximum current consumption: <48mA (1 input and 1 output); <60mA (1 input and 2 output); <90mA (2 input and 2 output)
■Working environment
◆ For indoor use only, install this instrument in a safe place.
◆ The instrument is protected to IP20 (IEC 60529 / EN 60529) and is suitable for use in a clean, dry environment.
Used internally.
◆ The ambient temperature is -20~60°C (continuous operation), and the relative humidity is 5~95% RH (no condensation) to ensure the instrument has sufficient service life.
■General safety measures
◆ When you install or remove the meter, turn off the power and disconnect the signal to ensure safety.
◆ Do not apply a load to the meter that exceeds its design capabilities.
◆ It is strictly forbidden to disassemble the instrument or change the circuit device to prevent the instrument from failing or malfunctioning.
◆ If there is instrument damage, improper load or malfunction, stop the instrument and immediately withdraw it.
■ Wiring
◆ The wiring cable of the instrument should be away from electromagnetic interference sources (for example: relay drive cable, high frequency line, etc.).
◆ The wiring cable and the electromagnetic interference source cannot be installed in the same pipe.
◆ The wiring cable is a single-core or multi-core cable with a section of 0.5~2.5mm2. The insulation strength of the wiring cable should be greater than 500V.
