Burndy 9150 4-Channel BNC Controller Card RPII20U3ORB-I SD8752 Module

Burndy 9150 4-Channel BNC Controller Card RPII20U3ORB-I SD8752 Module

The Burndy 9150 is a multi-channel BNC controller card designed for use in modular instrumentation and data acquisition systems. The card plugs into a backplane via a high-density edge connector (Burndy RPII20U3ORB-I) and presents four BNC connectors on a front-panel bracket, labeled 0, 8, 16, and 24, for signal input or output. The board carries a mix of discrete passive components, Sprague film capacitors, resistor networks, and a crystal oscillator, indicating an analog signal conditioning or timing/control role within its host system.

Applications

Burndy is well known as a connector and interconnect manufacturer, and the 9150 card uses a Burndy backplane connector as its primary interface — placing this card in the category of modular instrumentation cards designed to slot into a dedicated chassis or rack system. Cards of this type are used to route BNC-terminated analog signals (such as sensor outputs, trigger lines, or low-frequency waveforms) from front-panel connectors to a backplane bus for acquisition, switching, or conditioning. The four labeled BNC channels (0, 8, 16, 24) suggest the card occupies a defined slot address within a larger multi-card system where channel numbering is sequential across cards. This style of modular BNC I/O card was common in data acquisition, automated test equipment (ATE), and industrial control platforms from the late 1980s through the 1990s. These systems are still encountered in legacy test and measurement installations, scientific instrumentation, and industrial automation environments where original-format replacement or spare cards are needed to maintain operational continuity.
