FAQ

Q: How many relay outputs does this module provide?
A: Supplier data conflicts. Most sources list 16 channels; PLCMasters lists 8. Verify your specific module revision and system requirements.

Q: What base module do I need?
A: The 1C31219G01 relay module pairs with the 1C31223G01 Relay Output Base for field wiring termination.

Q: Can this module be replaced without shutting down the system?
A: Yes, Emerson designs Ovation modules for hot-swappable replacement in many configurations. Verify your chassis supports hot-swap before attempting online replacement.

Installation Guidelines

1. Install the module into an available Ovation I/O rack slot.
2. Pair with the 1C31223G01 Relay Output Base for field wiring.
3. Connect relay output wiring per the system diagram and load requirements.
4. Verify relay operation via Ovation diagnostics and physical load testing.

Selection Tips

• Select 1C31219G01 for discrete relay output control in Ovation systems.
• Verify channel count (8 vs. 16) against your system BOM before ordering.
• Confirm load current and voltage ratings match your field devices.
