Emerson Ovation 1B30023H02 | 1B30023H02 I/O Bus Terminator

Emerson Ovation 1B30023H02 Input/Output Bus Terminator Module

The 1B30023H02 (Part # 1B30023H02) is an essential passive electronics module within the Emerson Ovation™ Distributed Control System (DCS). Specifically designed for the Ovation I/O subsystem, this bus terminator is required to maintain signal integrity across the I/O backplane or extended branch. By providing proper impedance matching, the 1B30023H02 prevents signal reflections and electrical noise from corrupting data transmission between field modules and the Ovation controller. It is a critical hardware component for ensuring the deterministic performance required in high-availability environments like power plants and water treatment facilities.
