Allen-Bradley 1756-IA16 is a ControlLogix digital input module with 16 channels that reads discrete AC signals from field devices. Designed for 120/240 VAC inputs, it integrates into the 1756 I/O architecture to feed the PLC with real-time on/off status. The module supports an operating temperature range of 0 to 60 °C (32 to 140 °F) and a non-operating range of -40 to 85 °C, making it suitable for standard industrial environments; common applications include wiring 120 VAC or 240 VAC switches, relays, and sensors to monitor equipment status for centralized control.
