Cypress SPX-7400R Fiber READR Input/Output EXTENDR Multimode

Keep single-door and gate access points secure and reliable across long distances with the Cypress SPX-7400R multimode fiber reader extender. This Suprex reader expansion module converts Wiegand reader I/O to a supervised fiber link, delivering uninterrupted authentication and tamper monitoring for security and surveillance systems. Designed for practical deployments, the SPX-7400R operates on 8–16 VDC, ships with a remote unit, and fits into tight locations with a compact footprint (approx. 4.75" x 3" x 2"). Its robust aluminum housing protects electronics in industrial and outdoor-adjacent applications while multimode fiber connectivity eliminates EMI and ground loop issues often encountered with copper runs. Seamless compatibility with Cypress EXP-2000 expansion modules makes it easy to scale reader capacity across gates, doors, and perimeter access points. Ideal for access control integrators, facilities managers, and security installers who need dependable, supervised reader links over fiber. Add the SPX-7400R to your next access control or surveillance deployment to extend reach without compromising monitoring or system integrity.
