The ICP DAS ET-7044 provides 8 wet contact digital input channels and 8 sink-type digital output channels. It features optical isolation for 3750 Vrms of transient over-voltage protection but doesn’t provide channel-to-channel isolation. Each input channel can be used as a 32-bit counter and each output channel can drive 300 mA load.

The power-on value and safe value of digital output channel are programmable; the ICP DAS ET-7044 can safely be used in applications where hazardous voltages are present.
