Together with the M4000 Advanced multiple light beam safety device, the UE403 muting switching amplifier forms an efficient solution for remote, conventional muting applications with automated material transport. Its integrated functions, which can be configured easily via the RS-232 interface using a computer, and the simple on-site connection of the muting signals and control switches to the UE403 muting switching amplifier make it possible to implement access protection solutions with muting with maximum availability.
