R-16DI-8DO-P is a mixed digital module with dual 10/100 Mbps Ethernet ports. It is designed for flexible wiring needs, small installation space, high I/O density applications with built-in Ethernet networking. R-16DI-8DO-P has 16 PNP/NPN digital inputs and 8 digital relay outputs with maximum 30 V / 1 A range. The module has insulation between inputs, outputs and the remaining low voltage circuits of 1,500 Vac. The configuration can be made through CODESYS softPLC software and TiA Portal/Simatic Step7 design environment. R-16DI-8DO supports PROFINET IO communication and can be connected in Ethernet daisy chain mode with fault-bypass to ensure Ethernet connection even in case of failure of a module in the chain.

PROFINET (standardized IEC 61158 and IEC 61784) is oriented to applications in production automation, drives, automotive, food, packaging and logistics. Further application areas are emerging in the marine, energy and rail sectors. The use of PROFINET IO minimizes the costs of installation, design and commissioning of machines and plants. PROFINET IO also offers ease of expansion and high availability due to independent management of production units and low maintenance requirements.
