The ET-7065 provides 6 wet contact digital input channels and 6 form A PhotoMOS relays. It features optical isolation for 3000 Vrms of transient overvoltage protection and doesn't have channel-to-channel isolation. Each input channel can be used as a 32-bit counter. The power-on value and safe value of the PhotoMOS relay are programmable. It can safely be used in applications where hazardous voltages are present.
