Module 2 cổng Ethernet Modbus TCP 8 kênh đầu vào số (DI) AC/DC ICP DAS ET-7258 CR
The ET-7258 provides 8 AC/DC digital input channels. Each input channel can be used as a 32-bit counter. It features optical isolation for 2500 VDC of transient overvoltage protection but doesn’t provide channel-to-channel isolation. It can safely be used in applications where hazardous voltages are present.
