Specifications

A.1.4 Power supply

The Model 1700/2700 transmitter’s power supply:

•Has a self-switching AC/DC input

•Complies with low voltage directive 2006/95/EC per EN 61010-1 (IEC 61010-1) with amendment 2

•Meets Installation (Overvoltage) Category II, Pollution Degree 2 requirements

•Has an IEC 127–1.25 slowblow fuse

AC power requirements

85 to 265 VAC, 50/60 Hz, 6 watts typical, 11 watts maximum

DC power requirements

•18 to 100 VDC, 6 watts typical, 11 watts maximum

•At startup, transmitter power source must provide a minimum of 1.5 amps of short-term current at a minimum of 18 volts at the transmitter power input terminals

•Minimum 22 VDC with 1000 feet (300 meters) of 18 AWG (0,8 mm2) power supply cable

A.1.5 Environmental requirements

Ambient temperature limits

•Operation: –40 to +140 °F (–40 to +60 °C)

•Storage: –40 to +140 °F (–40 to +60 °C)

Display responsiveness decreases, and display may become difficult to read, below –4 °F (–20 °C). Above 131 °F (55 °C), some darkening of display may occur.

If possible, install the transmitter in a location that will prevent direct exposure to sunlight.

Different ambient temperature requirements may apply when installing the transmitter in a hazardous area. Refer to the approval documentation shipped with the transmitter or available on the Micro Motion web site.

Humidity limits

Relative humidity between 5 and 95%, non-condensing at 140 °F (60 °C)

Vibration limits

The transmitter meets IEC 68.2.6, endurance sweep, 5 to 2000 Hz, 50 sweep cycles at 1.0 g

A.1.6 Ambient temperature effect

On analog outputs ±0.005% of span per °C

A.1.7 EMC compliance

The transmitter complies with the following EMI effects standards:

•NAMUR NE21 (May 1999) with the exception of Voltage Dip when powered by 24 VDC

•Complies with EMC directive 2004/108/EC per EN 61326 Industrial
