Mod e l 2108i
1/8 DIN (96 x 48mm)
MODEL
In d ica tor a n d Ala rm Un it
The 2108i provides accurate measurement and display of
temperature and other process variables in a standard 1/8 DIN panel
format. Two alarm relay outputs are provided for operator alert and
process protection.
Id e a l fo r :
• Te m p e ra ture in d ica tion
• Proce ss in d ica tion
A universal input allows selection of nine internally stored
thermocouple types. Other input linearisations may be factory
downloaded. Linear, process inputs are scaleable to the desired
display range. Keylock and passwords prevent unauthorised access to
configuration and alarm settings.
• Ove r-te m p e ra ture
p rote ction
• Proce ss va lue trip un it
A large, red or green LED display gives good visibility in low and
high ambient lighting.
New alarms can be acknowledged and old alarms reset by a front
panel button or an external contact closure input.
Three internal alarm setpoints are provided. They are configurable
as high, or low, or rate of change alarms. Any combination of the
three internal alarms can activate the two relay outputs. Latching or
non-latching operation can be selected and alarm delays can be
applied. A special mode known as ‘alarm blocking’ is available. In
this mode, after power on, the process value must first enter a good
state before the alarm becomes active. This is particularly useful for
low alarms which can be ‘blocked’ while the process is warming-up.
Calibration accuracy is preserved with a self-correcting input circuit,
while a User Calibration facility allows offsets to be applied to
compensate for sensor and other system errors.
