R-16DI-8DO is a mixed digital module with dual Ethernet ports 10/100 Mbps and programming Micro USB front port.

The instrument is designed for flexible wiring needs, reduced installation spaces, high density I / O applications with networking Integrated Ethernet.

R-16DI-8DO counts 16 PNP / NPN digital inputs also configurable as totalizers @ 32 bits and 8 digital relay outputs with maximum range 30 V / 1 A.

All totalizers are stored in non-volatile memory (FeRAM). The module is equipped with isolation between inputs, outputs and remaining low voltage circuits equal to 1.500 Vac. The configuration can take place via Seneca Studio software and web server with support HTML5. IP address and firmware version associated with the single module can be identified on a LAN via Seneca Studio.

R-16DI-8DO supports both ModBUS TCP-IP and serial communication RS485 with ModBUS RTU protocol.
