The CommandFusion HRY2 module features 2 high voltage, high-amperage (250V AC, 15A) relay ports, and comes with on-board screw terminals for secure connections to external relay-controlled high-voltage devices. Plug the module into a CommandFusion modular controller to add relay control ports to your system. Need more relay ports? Just add another module.
Large Terminals for High Gauge Wiring
The HRY2 module uses on-board captive screw terminals for wire connections. This allows secure termination of thicker gauge wiring used in high-voltage, high-amperage installations.
As with all CommandFusion products, the communication protocol is open and available to all. Relay modules have simple commands for setting the relay states on, off, toggling and pulsing.
Power On States
Each relay port can be configured to be in ‘open’, ‘closed’ or ‘resume last state’ on power up. As the relays are latching (polarized), they will remain in their open or closed state even when power is lost.
Most relay control systems allow relays to be set on or off, and usually require high level programming on a control processor to perform anything else. CommandFusion relay control protocol includes additional functionality such as a simple toggle command (making it unnecessary to keep track of the relay state for basic toggle actions) and a pulsing command to pulse the relay closed for a time period, then opening again (of course, the time period is customisable as part of the protocol). Relay control has never been this easy!
