temperature indication process indication over-temperature protection process value trip unit 2108 i model indicator and alarm unit eurotherm ontrols universal input covers a wide range of temperature and process inputs two alarm relay outputs for operator alert and plant protection wide-range 85-264v ac, can be installed world-wide supply plug-in from front rapid replacement - reducing downtime front panel configuration easy, on-site set-up tactile buttons friendly operation three year warranty low ownership cost ideal for: features: model 2108 i 1/8 din (96 x 48mm) the 2108 i 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. 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. 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. indicator and alarm unit
