SB-B31

4 to 20mA Loop Powered

31 Segment Bargraph

in a 1/16 DIN Case

General Features

Compatibility

Elegantly simple 4 to 20mA loop powered bargraph.

Low loop drop of only 4V.

Needs no external power supply.

The SB-B31 bargraph has a matching DIN case style that is complementary to the Lynx, Leopard and Tiger family of meters. The SBB31 is the economical solution for displaying 4 to 20mA current loops on a bargraph display.

Choice of red, green or red/green color options.

4 to 20mA

Connectors are supplied by Texmate with the bargraph.

Pin 1 - Current Loop High Input: The 4-20mA current loop is applied to Pin (1) and returned from Pin (2). If reverse polarity is applied no damage will occur; however the meter will not operate (this condition should not be maintained for extended periods). The maximum loop drop is 4V.

Pin 2 - Current Loop Low Return: The 4-20mA current loop is returned from Pin (2). At 4mA the bargraph has one segment ON. At 20mA the bargraph has all segments ON. The maximum loop drop is 4V.

Signal Conditioning Components

SPAN Potentiometer (Pot)

The 15 turn SPAN Pot is on the left side (as viewed from the back of the meter). Typical adjustment is 100% of the input signal range.

ZERO Potentiometer (Pot)

The ZERO Pot is to the right side (as viewed from the back of the meter). It enables the Digital Display Span to be offset 50% of the input signal range.

Calibration Procedure

Apply an input of 4mA. Adjust the ZERO pot until the extreme left or bottom LED is ON. Apply 20mA input.

Adjust the SPAN pot until all LEDs are ON. The bargraph is now calibrated.

Power Supply

The SB-B31 Bargraph is powered from the 4 to 20mA input signal. NO EXTERNAL POWER SUPPLY IS REQUIRED. The maximum loop drop is 4V.
