The field display 2800-2026 is designed for analog signals in cumulative counting applications. The display indicates flow volume per a time unit and it can be freely scaled in the desired engineering units via front panel keys.
The display has bright red 20-mm-high LED digits, the readability of which is about 10 metres. Display memory stores the counted value in memory for one week without power supply.
The preset function makes it possible to use the totalizer as a batch controller as well. Counting can be done upwards to the preset value or downwards from the preset. Alarm relays may control other devices. New counting can be started automatically or manually via an external key.
There are two power supply possibilities, one for 85...240 VAC and the other for 24 VDC, both galvanically isolated from input/output. Case protection is IP65.
The totalizer and batch controller is also available for pulse sensors, model 2800-2061, a separate data sheet available.
