The board supports the switching of various voltages in the range from 35 up to 280 Volts AC can be switched directly by the personal computer . The solid state relays (SSR) are able to switch AC currents of 2 Amps (16 Amps with separate cooling) and are internally separated from the hardware by opto couplers.
These card can be used to switch all AC circuits in the range from 35 to 280 V by the PC. Therefore light, drives or pumps can the controlled by the PC.
"Galvanically separated" means that the components separated this way have no electric connection to each other. Therefore, the computer can not be destroyed by a voltage connected to the card.
