Featuring four individually addressable relays, the PC-PRO-RELAY-4 expands control from a Pro Control system to connected electronics ranging from amplifiers to window coverings. Using discrete infrared control, each relay can be triggered from Pro Control handheld remote controllers, processors or even third-party infrared repeater systems. 
Pro Control Wireless Zigbee Range Extender
The PC-PRO-RFZ extends the two-way link between the PC-PROLINK-Z processor and PC-PRO24-Z remote, providing reliable control and feedback to the remote for information such as song metadata, volume level, lighting control, and more.
In larger installations, multiple PC-PRO-RFZ wireless range extenders can be added by simply powering each from an electrical outlet. The devices will then create a reliable wireless network that instantly adapts to the surroundings to keep the communication path open and reliable. A detachable wall-mount bracket makes for a clean and easy installation.
