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:

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.
