Ethernet I/O Module/Modbus TCP/16 DI/2 LAN

Remote I/O module with Ethernet - Modbus TCP/UDP interface
Built-In Webserver: configuration, monitoring with standard Webbrowser
2-Port Ethernet Switch for Daisy-Chaining
I/O Pair Connection: Ethernet Tunnel between input and output.
16 isolated digital input channels (wet or dry contact) with 32-bit counter
Power Supply: 12 ~ 48 VDC, or PoE (only PET-7251)
DIN-Rail Mounting

The ET-7051/PET-7051/ET-7251/PET-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.
