DETECTION RANGE—
0 to 100 ppm
RELAY CONTACTS (OPTIONAL)—
Three Alarm relays: Form C, 5 amperes at 30 vdc.
Selectable normally energized or de-energized as a
group; low and auxiliary alarm selectable together for
latching or non-latching contacts, high alarm contacts
are always latching.
One Fault relay: Form C, 5 amperes at 30 vdc. Normally
energized for no fault condition with power applied to
device.
TEMPERATURE RANGE—
Operating: –40°F to +167°F (–40°C to +75°C).
Storage:
–67°F to +185°F (–55°C to +85°C).
WIRING—
18 AWG minimum is recommended for power wiring to
the transmitter. Larger diameter wire may be required
to maintain a minimum of 16 vdc at the transmitter for all
operating conditions. Maximum wire size for terminals is
12 AWG.
