Built-In Transmitter Excitation Supply
Model 2002B-E is a high-resolution digital process monitor which incorporates an electrically-floating supply for powering transmitters, active transducers and bridges. In many cases, this built-in supply can eliminate the need for a more expensive external supply. The output voltage is adjustable from 10 to 24 V dc. Maximum output current is 50 mA at any voltage setting.

High-Resolution Process Monitor
Except for the excitation supply, the 2002B-E is identical to the 2002B-P, a low-cost 4 1/2 digit (+19,999-count) process monitor for indication-only applications. It provides extensive zero and span adjustments to measure signals such as 4-20 mA, 1-5 V and 0-10 V in engineering units. Scaling and calibration are easily accomplished in the field by multiturn potentiometers accessible behind the lens. Accuracy is up to 99.98% of reading.

Compact Case
The 2002B-E is housed in a 1/8 DIN case that requires less than 4.1 in (104 mm) behind the panel. A screw-terminal barrier strip for signal and power is standard.
