Keri Systems SB-593 2nd Door and I/O Expansion Board for PXL500, Tiger II Controller Satellite Board

Scale your access control and monitoring infrastructure quickly with the Keri Systems SB-593 Satellite Expansion Board. Designed for Tiger II controllers, this expansion board plugs directly onto PXL-series controllers (including the PXL-500) to instantly provide 8 additional general-purpose inputs and 4 outputs. With a simple jumper setting you can economically configure two of those I/O pairs for second-door control—ideal for adding an extra door, alarm zone, or relay without a separate controller.

The SB-593’s compact, surface-mount design and DC power operation simplify installation in indoor access control cabinets and security rooms. Integrators will appreciate native compatibility with PXL-250, PXL-500, PXL-510 and PXL-500G-1 controllers, which streamlines retrofits and new deployments. Use it to extend security, surveillance and monitoring capabilities such as door status reporting, auxiliary alarm inputs, or relay-driven devices.

Backed by a 2-year limited warranty and built by Keri Systems, the SB-593 is a cost-effective way to expand I/O and door control without adding complexity. Add the SB-593 to your next access control project or contact sales to specify it for retrofit and new-install applications.
