NORVI Controllers
NORVI X-DI16
The NORVI X-DI16 is a 16-channel digital input expansion module for the NORVI X Modular Controller. It provides protected 24 V DC digital inputs for industrial switches, sensors, and logic-level signals.
At its core, the module integrates a PCA9555 I²C port expander, allowing the NORVI X CPU to read input states efficiently via the internal expansion bus. With four selectable I²C addresses, up to four DI16 modules can be connected on the same bus, providing a total of 64 digital inputs per controller.
Designed for modular scalability and DIN-rail mounting, the NORVI X-DI16 delivers reliable, noise-immune, and space-efficient 16-channel input expansion, making it ideal for industrial automation and control applications.
