Product Description
The Allen-Bradley 1756-IA16I is a ControlLogix digital input module featuring 16 individually isolated channels designed for precise and reliable signal monitoring. Operating on a 120V AC nominal voltage, this module is ideal for interfacing with a wide range of industrial field devices such as switches, sensors, and push buttons. The individual channel-to-channel isolation prevents electrical cross-talk, ensuring maximum system integrity and high operational uptime across automated manufacturing environments.
