Information About 1771-IAN
The 1771-IAN belongs to the Allen-Bradley 1771 Universal I/O family and is designed to operate with PLC-5 processors in industrial automation systems. It provides 32 discrete input points arranged in four groups, delivering reliable detection of AC signals across an 85–138 VAC range. Each channel is protected by optoelectrical isolation and noise filtering to safeguard the controller from electrical interference and transient conditions. The module uses the 1771-WN wiring arm, allowing rapid module replacement without disturbing field wiring. With individual input status LEDs, it provides clear visual diagnostics for channel activity, aiding in troubleshooting and maintenance.
Key Features:
- 32-Channel Input Capacity: Supports four groups of eight discrete AC/DC inputs for compact and efficient field device integration.
- 120V AC/DC Operation: Compatible with 85–138 VAC field signals, enabling connection to a wide range of industrial switching devices.
- Noise & Transient Protection: Optoelectrical isolation and input filtering reduce electrical interference and safeguard internal electronics.
- Diagnostic Status LEDs: Each input includes a dedicated status indicator for fast troubleshooting and signal verification.
- Service-Friendly Wiring: Uses the 1771-WN wiring arm, allowing module swaps without disconnecting field wiring.
- Reliable Signal Timing: Provides typical 10 ms ON and 20 ms OFF delays for dependable AC signal processing.
- PLC-5 Compatibility: Designed specifically for PLC-5 processors and the 1771 I/O chassis platform.
- Industrial Durability: Built for continuous-duty operation in demanding automation and process control environments.
The 1771-IAN delivers the reliability and precision required for robust discrete signal handling in PLC-5-based industrial control systems.
