Description
The 5X00241G02 is a high-density, 16-channel Digital Input (DI) module designed for the Emerson Ovation Distributed Control System (DCS). This specific “G02” variant is typically configured for 24 V DC discrete signal sensing, allowing the controller to monitor the status of field devices such as limit switches, relay contacts, and pushbuttons.

Technical Implementation & Field Considerations
Contact Sensing and Wetting Voltage
The 5X00241G02 is designed to detect the state of dry contacts. In a typical installation, a 24 V DC “wetting voltage” is supplied to the field contact. When the contact closes, the current returns to the module’s input channel, completing the circuit and registering a “Logic 1” in the DCS database.
Sequence of Events (SOE) Capability
Depending on the specific Ovation software version and hardware configuration, this module can often be utilized for Sequence of Events recording. It can timestamp transitions with sub-millisecond precision, which is critical for post-trip analysis in turbine control or electrical substation monitoring. Verify that your specific 5X00241 revision supports the SOE resolution required for your application.
Diagnostic LEDs
The module front panel provides immediate visual feedback for troubleshooting:
-
Active (Green): The module is properly addressed and communicating with the Ovation Controller.
-
Error (Red): Indicates a hardware self-test failure or a configuration mismatch in the Point Builder software.
-
I/O LEDs (Yellow/Amber): Indicates the current state of each of the 16 inputs. If a field contact is physically closed but the LED is off, check for a blown fuse on the baseplate or a broken field wire.
Field Wiring and Baseplates
This module must be plugged into an Ovation Electronics Base. The wiring is determined by the baseplate type. In many “G02” deployments, the 24 V DC power for the contacts is distributed through the baseplate backplane, reducing the amount of individual power jumping required at the terminal blocks.
Maintenance and Replacement FAQ
Can I hot-swap this module while the plant is running?
Yes, the 5X00241G02 supports hot-swapping. However, pulling this module will immediately cause all 16 digital points to report “Bad Quality” or go to their fail-safe state in the controller logic. If these points are used in interlocks (e.g., “Pump Running” feedback), the logic may trigger a trip. Always force or bypass critical points in the software before physical removal.
What is the difference between G01 and G02?
In the Ovation numbering scheme, “G” (Group) variations typically denote different voltage levels or hardware revisions. While G02 is standard for 24 V DC, other groups may be rated for 48 V DC or 125 V DC. Never mix voltage levels; installing a 24 V module into a 125 V circuit will result in immediate hardware destruction.
Why is my “Error” LED flashing?
A flashing red Error LED usually indicates that the hardware ID of the module does not match what is configured in the Ovation configuration tools. This often happens if a different revision of the module is used during a replacement.
Does this module require external fuses?
Most Ovation baseplates provide individual or group fusing for the field side of the DI module. If an entire module appears “dead” but the Active LED is on, check the glass fuses located on the associated baseplate or the power distribution terminal block.
Do you need the terminal assignment diagram for the 16 channels, or are you looking for the specific software configuration parameters for an SOE (Sequence of Events) application?
