BN-Series
General Features
The BN-35I is a low cost pin for pin functional replacement for the Newport model 215, with many more features. It is a 312 digit voltmeter in a compact 96x24mm case with an internal isolated power supply. 5V, 12V, 15V or 24VDC power options are available.The case has a short depth of just 2.83 inches (72mm) behind the panel.
The meter has four user-selectable ranges of 200mV, 2V, 20V and 200V. The BN-35I may also be calibrated at the factory for these ranges or specially scaled for other ranges (see Ordering Information below). Provision to offset the zero is also available as an option for 4-20mA signals.
The display is shipped standard with red LEDs, but green LEDs or super bright LEDs for high ambient light environments are also offered. Display Segment Test, Display Blank and Hold Reading are standard features.
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.
