q Voltage variations must not exceed ±10% of the nominal one.
q Input/output are insulated up to 500V
q The output 4-20 mA (optional) is electrically connected
q
The converter can be installed inside or outside buildings
q Altitude: from –200 to 2000m (from -656 to 6560 feet)
q 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.
