	2772-0035: ± 20 % of reading ± 0.02 ppm.
PHYSICAL	7" Depth x 11.75" Width x 7.875" Height
Dimensions:
	(178mm D x 298mm W x 200mm H)
Weight:	11.5 lbs. (5.2 Kg.).
Enclosure:	IP-55 with sealed glands (NEMA 4).
Cable Glands:	3 x for input/output cables. Pre-wired connector for Optional Printer.
POWER INPUT REQUIREMENTS
External Power Supply: 12VDC
Input Current:	Depends upon model and conditions.
Low Flow models:	(200cc/min or less) Cat.# 2772-0010/015/020/030/035/040/060/
	090/095/100/110/150 etc.
	Normal run current (charged battery)	=150–200mA
	Run current (discharged battery)	=500–700mA
High Flow models:	(700cc/min or less) Cat.#272-0120/160/175 etc.
	Normal run current, (charged battery)	=250–300mA
	Run current (discharged battery)	=600–800mA
OUTPUTS
Solid State ‘Relay’ Output:
Standard System:	1 Combined Gas/ Fault Alarm.
Optionally:	2 Gas Alarms plus 1 Fault Alarm, or
	Devices rated @ 1A./60 V DC max.	= 5A peak.
	Surge current (1 second)
	Turn on/off time	= 50, ms.
	On state voltage	= 1.5V DC
Logic:	Off state leakage at 60 V DC across the load = 200, ∝A
	Device normally ‘closed’, opens on alarm
Analog Output:	(with standard system software).
Standard:	4–20 mA is default on the instrument.
	0–1 V DC can be hardware selected.
	In both cases the minimum	= zero concentration,
	and the maximum value	= system range maximum.
