Display
INTERNALLY ISOLATED 24VDC power supply supports 9VDC to 36VDC power input.
Input protection: clamps current to 32mA; withstands up to 50V; reverse current is blocked; loop current flows when meter is not powered
International standard DIN 96x24mm case
Short depth case: 2.83" (72mm) behind panel
0.56" high red LEDs standard
Adjustable display brightness
Optional green, blue or extra bright red LEDs available
Display Hold and Test
Ideal for OEM applications
The BN-45CL420 is a streamlined 4 to 20mA current loop meter. It is specifically designed to be easily scaled and calibrated to almost any conceivable engineering unit, such as temperature, pressure, viscosity, flow rates, etc., without requiring component changes. Scaling defaults to 00.00 - 100.00(%); contact Texmate for your custome scaling needs.
The display is shipped standard with red LEDs, but green LEDs, blue LEDs or super bright LEDs for high ambient light environments are also offered. Display Segment Test and Hold Reading are standard features.
Compatibility
The BN-Series have a matching DIN case style that is complementary to the Lynx, Leopard and Tiger family of meters. BN-Meters are the OEMs choice for economical switchboard and process indication. For economy, each model is dedicated to a specific application and designed for quick and easy installation.

Decimal Point Selection
Display Test: All numeric display segments will light up when Display Test Pin 6 is connected to Common Pin 3.
Display Blank/Dim: If Pin 4 is connected to Common Pin 3, the display will be blanked out. If a 1K pot is connected between Pin 4 and Common Pin 3, the brightness of the display can be adjusted with the potentiometer.
Hold Reading: If Pin 5 is left unconnected, the meter will operate in a free-running mode. When Pin 5 is connected to the Hold/Test/Blank Common Pin 3, the meter will latch up. A/D conversions will continue, but the display will not be updated until the Hold Pin and Common pins are disconnected.
The BN-45CL420 ships from the factory with a isolated 24VDC power supply (9-36VDC input range).
ZERO Potentiometer (Pot) Optional
The Optional ZERO pot when installed is to the left of the SPAN pots (as viewed from the back of the meter). Typically it enables the displayed reading to be offset 1000 counts.
SPAN Fine Potentiometer (Pot)
The 15 turn SPAN Fine pot is the middle pot (as viewed from the back of the meter).
Typical adjustment is 20% of the input signal range.
Component Layout
Zero Span
Zero offset and Span header/jumpers are used for display scaling. Scaling defaults to 00.00 - 100.00(%); contact Texmate for your custome scaling needs.
P.N.: 75-DESCRIPTR
To customize the face plate, clear adhesive label containing various popular descriptors may be ordered. Choose the descriptor desired, peel off the adhesive backing and align the descriptor in the center right of the faceplate.
