Reliance 45C946 16-Point 24VDC Input Module

Reliance 45C946 Shark XL is a 16-channel, 24 VDC input module for Reliance Electric's Shark XL I/O family. It provides 16 sinking input channels that accept field signals at 24 VDC and feed them to the backplane for the controller, enabling reliable reading of sensors, limit switches, and other discrete devices in industrial automation. The unit mounts in a Shark XL I/O rack and includes a removable terminal block to simplify wiring, testing, and maintenance. As part of the Shark XL 24 VDC input lineup, the 45C946 sits with other 24 VDC inputs (such as 45C944 and 45C945) and follows standard 24 VDC wiring patterns shown in wiring diagrams for these models. With 16 dedicated inputs, it offers a compact solution for expanding legacy automation or integrating 24 VDC sensing into existing control schemes, delivering straightforward compatibility with XL-series controllers and backplanes. Typical applications include machine control, process monitoring, and safety interlock signaling on production lines where 24 VDC sensing is required.
