ELK M1XOVR 16 Output Expander, Voltage and Relays

For integrators and security professionals who need reliable expansion of control capabilities, the ELK Products M1XOVR 16 Output Expander delivers flexible output control for alarm, automation and surveillance systems. This control panel module adds 16 outputs—eight low-voltage triggers for sensors or auxiliary devices and eight SPDT relay outputs rated at 7A @ 30VDC and 10A @ 125VAC—so you can drive lights, locks, annunciators and third‑party equipment without extra panels. The expander operates on the M1 four‑wire data bus and supports up to 12 units per system for a total of 208 outputs, enabling large-scale monitoring and automation across commercial or residential sites. With a compact 6" x 3.3" x 0.8" footprint and 12V DC power, the M1XOVR fits easily into retrofit and new installations while maintaining RoHS compliance. Convert the eight voltage outputs to relays with the optional M1RB relay board for even greater flexibility. Enhance your security, surveillance and building automation projects by adding the ELK M1XOVR to your M1 Gold or M1EZ8 control panel—contact your ELK distributor or add it to your next system design.

• Expand system capacity quickly: adds 16 outputs (8 voltage, 8 relays) to M1 Gold or M1EZ8 control panels for flexible device control
• Simplifies integration: voltage outputs trigger low-current devices while SPDT relays handle heavier loads up to 7A@30VDC / 10A@125VAC
• Scalable and future-ready: supports up to 12 expanders on the 4‑wire data bus for a total of 208 outputs
• Installer-friendly: compact 6" x 3.3" x 0.8" footprint and 12V DC operation speed up deployment in commercial or residential sites
• Adaptable configuration: convert voltage outputs to relays with M1RB relay boards for custom security and automation needs
