The 1B30023H02 is an I/O branch terminator module for Emerson Ovation distributed control systems. It provides signal termination at the end of an I/O branch where no Attachment Unit Module (AUM) exists, preventing signal reflections and ensuring reliable communication across the local I/O bus.
| Specification | Details |
|---|---|
| Model Designation | 1B30023H02 |
| Product Type | I/O Branch Terminator Board |
| Compatibility | Emerson Ovation I/O bases |
| Power Input | +24V DC nominal |
| Redundancy | Supports redundant power configurations |
| Mounting Orientation | Fits both A and B sides of standard I/O bases |
| Primary Function | Terminates local I/O communication bus |
The 1B30023H02 maintains noise immunity and signal integrity on Ovation I/O branches. Its flexible mounting on either side of the I/O base simplifies installation and retrofitting, making it suitable for power generation and heavy industrial process control applications.
Why is this module necessary at the end of an I/O branch?
It prevents signal reflections caused by impedance mismatches, which can otherwise lead to communication errors or intermittent data loss.
Is this module compatible with all Ovation I/O bases?
Yes, it is designed for standard Ovation I/O bases and can be mounted on either side to suit branch layouts.
Does the module require external power?
Yes, it requires a +24V DC supply and supports redundant power feeds for enhanced operational reliability.
