Module 2 cổng Ethernet Modbus TCP 16 kênh đầu vào số DI ICP DAS ET-7251 CR
Features
Introduction
The ET-7251 provides 16 wet contact digital input channels. Each input channel can be used as a 32-bit counter. It features optical isolation for 3750 Vrms of transient overvoltage protection but doesn’t provide channel-to-channel isolation. It can safely be used in applications where hazardous voltages are present.
