OPERATiNG VOLTAGE—
24 Vdc nominal, operating range is 18 to 30 Vdc.
OPERATiNG POWER—
7 watts maximum.
Heater off:
2 watts @ 24 Vdc with alarm relays off and
4 mA output.
Heater off:
4 watts @ 24 Vdc with alarm relays on and
20 mA output.
Heater on:
5.5 watts @ 24 Vdc with alarm relays off
and 4 mA output.
Heater on:
7 watts @ 24 Vdc with alarm relays on and
20 mA output.
Heater function is not user configurable. Heater
turns on when the internal temperature drops
below –10°C.
Appropriate relays will be activated when a fault
or alarm occurs.
CURRENT OUTPUT—
Linear isolated 4-20 mA output with HART.
3.8 mA indicates calibrate mode.
3.6 mA or less indicates a fault condition.
Maximum loop resistance is 600 ohms at 18 to 30 Vdc.
CURRENT OUTPUT RESPONSE TiME—
Toxic gas mode:
Combustible gas mode:
Combustible gas - open path mode: T90 = <4 seconds.
CURRENT OUTPUT ACCURACy—
Toxic gas mode:
Combustible gas mode:
Combustible gas - open path mode: ≤0.01 LFL/M.
RELAy CONTACTS—
Three Alarm Relays: Form C, 5 amperes at 30 Vdc.
Selectable latching or non-latching.
Refer to Table 1 for range and
default settings.
WarnIng
When in non-latching mode, the control device
must latch the alarm output.
One Fault Relay:
Form C, 5 amperes at 30 Vdc.
Normally energized for no fault
condition with power applied.
RELAy RESPONSE TiME—
≤ 2 seconds.
