Before procurement teams confirm RTU-485, they typically review Siemens PLC, Delta Dvp14Ss211R and Delta VFD to double-check performance ratings, stock availability, and supplier credibility carefully.
Delta RTU-485 Programmable Logic Controller
The Delta RTU-485 Programmable Logic Controller (PLC) is a robust RS-485 Remote I/O Module designed for seamless expansion with DVP-S series I/O modules. It supports a 24 VDC power supply, Modbus ASCII/RTU data format, and a wide serial baudrate range from 1,200 to 115,200 bps. The module offers 500 VDC electrical isolation, a reliable 2-wire shielded transmission cable method, and durable IEC 61131-2 vibration/shock immunity. With a 3-pin removable connector and broad -25Β°C~70Β°C storage / 0Β°C~55Β°C operating range, it ensures stable field communication. Manufactured by Delta, within the Delta Programmable Logic Controller family, offered under the Delta DVP-S Series.
