power
LLV 18-30V 10W
‰ Voltage variations must not exceed ±10% of the nominal one.
‰ Input/output are insulated up to 500V
‰ The output 4-20 mA (optional) is electrically connected
‰ The converter can be installed inside or outside buildings
‰ Altitude: from –200 to 2000m (from -656 to 6560 feet)
‰ Humidity range: 0-100% (IP 67)
Consider the ambient temperatures more restrictive between converter and sensor.
* = For discontinuous use, the installation of a heating resistance is necessary.
1 = For liquid temperature > 60°C , ambient temperature max 40°C
130°C Cip (cleaning in place) is allowed up to 30’ (unlimited time if converter switch off)
