4 × high voltage non-latching relays.
General purpose relay control.
The RY4 module features 4 × 250V AC 5A non-latching relays. Perfect for general purpose relay control applications.
Simple to use.
Open protocol.
As with all CommandFusion products, our communication protocol is open and available to anyone. Relay modules have very simple commands for setting the relay states on, off, toggling and pulsing. » View CFLink Protocol Docs
Need more relay ports?
Just get another module.
The beauty of the modular controllers is their flexibility. Need more of a specific port? Get another module and plug it in.
Detachable terminals
for convenience.
The RY4 module uses detachable screw terminal blocks for wire connections. This allows for convenient removal.
Overview
The RY4 module features 4 high voltage (250V AC, 5A) relay ports, and comes with detachable screw terminal blocks for secure connections to external relay-controlled devices. Plug it into a modular controller to add relay control ports to your system.
Power On States
Each relay port can be configured to be in open, closed or resume last state on power up. Using the resume option, they will return to their open or closed state after a power loss.
Extended Functionality
Most relay control systems out there allow you to set relays on or off, and require complex programming on a control processor to perform anything else. Our relay control protocol includes additional functionality such as a simple toggle command (so that you don't have 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 so easy.
