2800-2012 is a field display for measuring mA or V signal or a potentiometer.

The reading is displayed with six digits, if desired. Fixed trailing zeros are available. The card features a freely adjustable lowpass filter, hold function, and tare function. An external switch or relay contact can be used to trigger the hold and tare functions.

2800-2012 supports several 2000 series auxiliary cards: an analog output card, a serial communications card, and two- or three-relay alarm cards. If the same device is equipped with two 2012 input cards, the combination is called 2212. It is possible to calculate a simple mathematical operation among the channels.
