Description:
The Allen‑Bradley 1794‑IC16 is a 16-channel non-isolated sinking digital input module belonging to the Flex I/O series of Rockwell Automation. It is rated for 48V DC nominal voltage, designed to accurately collect discrete signals from field devices such as proximity switches and limit switches. This module is compatible with terminal bases including 1794‑TB2, ‑TB3 and ‑TB3S, supports FlexBus communication, and can be seamlessly integrated into Rockwell PLC systems. It is widely applied in industrial automation scenarios like manufacturing and process control.
16-channel high-density design enhances signal acquisition capacity, ideal for multi-device monitoring scenarios
Non-isolated sinking input with 48V DC nominal voltage and a wide voltage range of 30‑60V DC, adaptable to various industrial sensors
Configurable input filtering from 0.25ms to 32ms with 1ms default, effectively suppressing field interference and ensuring stable signal transmission
Independent LED status indicator for each channel enables quick diagnosis and maintenance
Compliant with ATEX, UL and other international certifications, capable of withstanding 0‑55℃ industrial environment and adapting to harsh working conditions
