Overview
Configured for physical data communication between controllers and I/O drop assemblies in the Emerson Ovation DCS, the Emerson 5A26141G06 (5A26141G06 Local I/O Bus Cable) provides a dedicated cable connection for local bus signal transmission. The cordset uses DB9 connectors and supports an RS-485 compatible data format. Its 4.5 ft cable length provides a defined interconnection path between associated Ovation hardware assemblies.

DCS Communication and Signal Interface
The 5A26141G06 functions as a physical communication interconnect within an Emerson Ovation system. The cable carries local I/O bus signals through its DB9 connector interfaces and supports RS-485 compatible communication.
RS-485 communication uses differential signal transmission to support data exchange across the connected hardware path. Therefore, cable routing, connector engagement, and separation from high-noise power conductors affect the electrical installation environment.
This cable assembly does not perform 4-20 mA HART loop processing or channel-to-channel isolation. Instead, it provides the physical communication path required by the connected Ovation controller and I/O assemblies.
Frequently Asked Questions
Q: Does the Emerson 5A26141G06 require a separate power supply?
A: No separate cable power consumption is specified. The 5A26141G06 is a passive communication cable assembly.
Q: What connector interface does the 5A26141G06 use?
A: The cable assembly is specified with DB9 connectors for connection to compatible Ovation hardware interfaces.
Q: Can the 5A26141G06 be extended with an additional cable?
A: The supplied cable length is 4.5 ft. Additional cable extensions should only be evaluated against the communication and installation requirements of the connected Ovation hardware.
Field Installation Guidelines
Verify that both connected interfaces are compatible with the Emerson 5A26141G06 before installation. Align the DB9 connectors correctly and secure the connector retention hardware without applying excessive mechanical force.
Route the cable away from high-current conductors, switching equipment, and other potential electromagnetic noise sources where practical. Avoid sharp bends, crushing, excessive tension, and unsupported cable movement.
Inspect connector contacts and cable insulation before energizing the connected system. Do not modify the cable shielding or connector wiring unless the procedure is defined by the applicable Emerson Ovation system documentation.
