Series WHHC-27 Wireless Remote Control System provides a wireless bridge between a handheld transmitter and a relay receiver control panel. When a switch on the handheld transmitter is pressed signals are sent via a license free radio signal to a receiver unit up to 2 miles (Line-of-site) away. When the control panel receives the proper wireless signals from the handheld transmitter control relays inside the panel are energized to operate remote equipment such as a pump, valve, motor, wench or gate.

Application Example: Controlling 2 Remote Water Pumps
