Specifications
POWER SUPPLY REQUIREMENTS
Power Input			24VDC or 24VAC ±10% @ 50/60Hz
Power Consumption			10mA @24VDC (80mA w/ backlight on)
Polarity MUST be observed when connecting power.
If using 24VAC, the data and power cabling should be segregated and data run in screened cable (as shown on page 5 of datasheet).

ENVIRONMENTAL
Operating Temperature			32°F to 104°F (0 to 40°C) non-condensing
Storage Temperature			32°F to 122°F (0 to 50°C) non-condensing

ENCLOSURE
Housing is moulded from flame retardant plastics recognised by UL as UL94-V0. The housing is designed to maximise airflow to the onboard sensors. It should be mounted with a standard vertical C-Clip, or on a standard wall enclosure.
