Features:
- Terminates thirty-two 24 V DC status channels for Series 8 digital input processing.
- Optically separates field circuits from the control-system electronics.
- Applies a five-millisecond input delay to reject brief contact or wiring disturbances.
This part is the coated nine-inch non-redundant IOTA and not the removable digital input electronics.
It gathers switch, interlock and equipment-state signals for C300 control strategies.
Terminal commons, field source and wetting resistance should be reviewed against each connected device before exchange.

- Motor-control centres use the channels to report run, trip and permissive contacts to Experion.
- Process skids collect valve limit switches and pressure-switch states through the 32-point termination assembly.
- Shutdown-support panels can isolate the controller electronics from 24 V field wiring while retaining rapid event response.
- Defined ON and OFF thresholds distinguish valid field states from leakage or open wiring conditions.
- The five-millisecond filter prevents very short transients from appearing as stable controller inputs.
- Channel status is supervised through the paired 8C-PDILA1 electronics in the Experion system.
- System-to-field isolation withstands the documented 1000 V AC RMS or ±1500 V DC level.
- Optical isolation prevents normal field potential from being carried directly into the control electronics.
- Hot removal and insertion must follow the plant procedure and hazardous-location restrictions for the installed cabinet.
- Coated construction is intended for the specified Series 8 industrial control environment.
- The nine-inch assembly requires enclosure space and airflow matching the existing carrier arrangement.
- Field conductors must remain within approved insulation, temperature and terminal-current limits.
