The Eurotherm 2108i horizontal mount indicator and alarm unit provides accurate measurement and display of temperature and other processing variables in a standard 1/8 DIN panel format. The two alarm relay outputs are provided for an operator alert and process protection.

A universal input allows selection of nine internally stored thermocouple types. Other input linearization may be factory downloaded. Linear, process inputs are scalable to the desired range.  Keylock and passwords prevent unauthorized access to configuration and alarm settings.

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 these 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.
