Reliance Electric 45C964 Controller

The Reliance Electric 45C964 Shark XL 16-Point Output Module is a transistor-type digital output block designed for use with Reliance Electric’s Shark XL automation controllers. It provides sixteen independent 24 VDC outputs with a nominal voltage of 24 VDC and an operating window of 5–27 VDC, enabling compact, centralized control of field devices from a single module. Each channel is opto‑isolated and fed through a removable terminal block, supporting safe, easy field wiring in industrial environments. The module is UL listed and part of the Shark XL family, reflecting its heritage in Reliance Electric control systems, though it is a legacy part no longer manufactured by Reliance Electric. Key electrical characteristics include 16 channels, 24 VDC nominal output, 5–27 VDC operating range, a maximum inrush current of 3 A, and leakage current limited to 0.1 mA; these specs help define drive capability and fault margins in panel installations. The 45C964 is closely related to the 45C962 and 45C963 variants, which share the same form factor but provide different output configurations, while the 45C964 specifically delivers 24 VDC outputs across its 16 channels. The unit includes its own removable terminal block for straightforward installation and maintenance, making it a practical choice for Shark XL deployments requiring a compact, multi‑channel 24 VDC output interface across a broad range of industrial applications.
