the LA6 POE LED Signal Tower - the most advanced, fully customizable signal tower series now with Ethernet (Modbus/TCP UDP) connectivity. The LA6-POE is able to read and write all necessary data through a network connected Ethernet cable. Also, it supports PoE (Power over Ethernet), so there is no more need for input and output modules for PLCs or running wires. The LA6 series features multi-color LEDs able to display 21 colors, 11 buzzer, animated pattern capabilities (using the internal timer function) and endless flash rate settings to fit users’ unique signaling needs. No longer are users limited to the common 3 or 5 stack lights with preset colored light modules. Instead the LA6 features clear modules equipped with multi-color LEDs, which enable users to customize the signal tower specifically for their application.
