The Kadtronix family of smart relay controllers provide intelligent switching for any number of uses including commercial and residential applications. These devices feature digital microcontroller-based processing, coupled with Form C relay for 5A switching capacity. Simple to install and requiring no complicated setup or detailed instruction, the product is available in several models including wired and wireless variations:

• Basic Smart Relay Switch (BSRS)
• Wireless Smart Relay Switch (WSRS)
• HVAC Smart Relay Switch (HSRS)
  

The Basic Smart Relay Switch (BSRS) provide inputs for accepting up to four (4) hardwired switch(es) including toggle, pushbutton, magnetic reed, limit switches, thermostats, etc. Relay activation occurs when “trigger” is detected on any switch input (i.e., a normally-open switch closes, or normally-closed switch opens). Each input can accept a single switch device or multiple switches wired in a zone configuration with multiple switches in series (N/C) or parallel (N/O).

Notes:

• The controller can be configured to accept either normally-open or normally-closed switches.
• Wired-switch cable runs should be limited to 100 ft. max. at each input. Twisted-pair shielded cables recommended.

The BSRS features user-configurable settings comprised of sixteen (16) onboard DIP switches, allowing you to tailor the unit's operation to the particular application. Define trigger mode (normally-closed vs normally-open), delays, audible notification, and more!

Wireless variations (WSRS & HSRS-RF) include all features and options of the BSRS while also permitting relay activation or deactivation via RF signals.Compatible wireless peripherals include handheld key fob transmitters and door/window sensors.

The Wireless Smart Relay Switch (WSRS) provides relay control via wireless peripherals including key fob transmitters and door sensors. Up to eight (8) wireless peripherals can be paired for use with the WSR controller.

The HSRS is an energy-saving system intended for use with HVAC systems. Available in wired and wireless variations, the HSRS performs automatic shutoff when doors or windows remain open for a period of time. The HSRS is a specialty product that includes relevant accessories and peripherals. For details, click here.

User wiring is performed at convenient screw terminals. The table below lists the terminal connections:
