SENTRY TIM-100/120

Note:

•

A TIM-100 is shown above. Except for items 3 and 4, the descriptions listed also apply to the
TIM-120. Access to the display and keypad on a TIM-120 is provided through the use of a
Program Module available separately.

SENTRY TIM-100/120

is a

microprocessor-based interface
used in conjunction with the Sentry
exhaust controllers (SENTRY 1000,
1510, and 9000). The TIM-100/120
provides the user with the ability to
interface with the controller through
direct manual input from the user or
through electronic communication
from the process equipment.
