Product Description P/N: 1794-IA8
Description
The Allen-Bradley 1794-IA8 is a FLEX I/O digital input module designed for 120 VAC applications. It provides eight non-isolated input points that convert AC signals into logic-level signals for use by a controller. Compact and flexible, this module mounts on a DIN rail and is commonly applied in distributed I/O systems across industrial automation environments.

Information About 1794-IA8
The 1794-IA8 is part of the Allen-Bradley FLEX I/O 1794 series, built for modular and space-efficient distributed I/O. It supports eight input channels with operating voltage from 85 to 132 VAC at 47–63 Hz, and a nominal voltage of 120 VAC. Each input requires a minimum of 65 VAC to switch ON and recognizes OFF below 43 VAC. The module draws 30 mA from the FlexBus at 5 VDC and dissipates a maximum of 4.5 W at 132 VAC. It includes eight yellow LED indicators for channel status and is compatible with multiple terminal base units, including 1794-TB2, 1794-TB3, 1794-TBN, and 1794-TBNK. With an isolation rating of 2150 VDC for one second and built-in filtering (8.4 ms ON delay, 26.4 ms OFF delay), the 1794-IA8 ensures reliable operation. It operates from -20 to 55 °C with 5–95% non-condensing humidity, carries approvals for Class I, Div. 2 hazardous locations, and provides robust vibration and shock resistance.
Key Features:
- Series: Part of the Allen-Bradley FLEX I/O 1794 distributed I/O family.
- Inputs: 8 non-isolated digital AC inputs.
- Voltage Range: Operates at 85–132 VAC, nominal 120 VAC.
- Signal Thresholds: 65 VAC minimum ON, 43 VAC maximum OFF.
- Current: Typical 12 mA at 120 VAC, 60 Hz.
- FlexBus Load: 30 mA at 5 VDC.
- Diagnostics: 8 yellow LED status indicators for channel monitoring.
- Mounting: DIN rail or panel mount with compatible terminal bases.
- Environmental: Operating range -20…55 °C, 5–95% RH, rated for Class I, Div. 2 hazardous areas.
- Protection: IP20 open-type module with 2150 VDC isolation.
The 1794-IA8 delivers reliable 120 VAC input capability for distributed FLEX I/O control systems in industrial automation.
