- Eight 120 V AC field inputs for FLEX I/O distributed stations
- One nonisolated sinking-input group with eight channel indicators
- Selectable input filtering for response-time and noise-rejection requirements
1794-IA8 brings a group of eight AC field inputs into a distributed FLEX I/O station without consuming a chassis slot.
Its selectable filtering helps the control system balance response time against rejection of short AC input transitions.
Plan the terminal-base choice, keyswitch, 120 V AC field circuit, input grouping, and enclosure environment as one installation.
Availability, condition, price, and shipping time for 1794-IA8 are confirmed during quotation.

- Eight 120 V AC inputs operate as one nonisolated field group.
- Each channel reports its on or off state through the FLEX I/O adapter.
- The common field circuit must suit the installed AC signal sources.
- Selectable filtering controls how long an AC transition must persist before recognition.
- Use the original project value when replacing a configured module.
- Investigate field noise and wiring before increasing filter time to mask unstable signals.
- Mount the module on a documented 1794 terminal base with keyswitch position 8.
- Remove hazardous power before connecting or separating field conductors.
- Preserve terminal numbering, common wiring, grounding, and station slot order.
- Acquisition of compatible 120 V AC switch and contact states in distributed FLEX I/O stations.
- Monitoring of eight grouped AC field signals through a FLEX I/O network adapter.
- Machine or process input collection where selectable AC input filtering is required.
