The 1791-32AO is a discrete input module from the 1791 Block I/O series, designed for high-reliability industrial automation applications. It features thirty-two (32) inputs organized into four (4) groups, with eight (8) channels per group, allowing flexible and efficient wiring for distributed control systems. The module supports Remote I/O (RIO) communication protocol, enabling seamless integration into existing control networks.
This module operates with an input voltage of 120VAC and nominal input current of 11 mA. The on-state voltage range is 79-132VAC at 47-63 Hz, while the off-state voltage is limited to 35V maximum. Input on-state current reaches 12.3 mA at 132V maximum, and off-state current is 2.3 mA minimum, ensuring accurate and reliable input detection for process control.
Powered by an external supply of 85-132VAC at 150 mA, the 1791-32AO module dissipates 13.62 Watts of power (46.44 BTU/hr). It does not provide outputs per block, focusing solely on discrete input monitoring. This makes it ideal for applications where precise input state detection and robust thermal performance are critical in distributed or block I/O control systems.
