Emerson Ovation 1C31205G01 Remote Node Base Assembly

Product Description

The 1C31205G01 is a foundational hardware component for the Emerson Ovation Distributed Control System (DCS). This Remote Node Base Assembly is designed to house and provide the electrical backplane for remote I/O modules, allowing the Ovation system to extend its reach to distant process areas without requiring a full controller cabinet. It acts as the physical mounting point and communication interface for the remote node electronics, bridging field signals back to the main Ovation Controller via the Fast Ethernet or Fiber Optic remote I/O link.

Common FAQ

What is the difference between a local I/O base and this Remote Node Base?While a local I/O base connects directly to the controller's local branch, the 1C31205G01 is specifically designed for "Remote Nodes." These nodes utilize specialized communication modules (like the 1C31203 Remote Node Controller) to transmit data over long distances via Ethernet or Fiber, rather than a local bus.

Does this assembly include the electronic modules?No. The 1C31205G01 is the Base Assembly (the "housing and backplane"). The electronic modules (such as the Remote Node Controller or I/O cards) must be purchased separately and plugged into this base.
