Allen-Bradley 20-COMM-R

The Allen-Bradley 20-COMM-R is a versatile communication adapter designed to enhance PowerFlex AC drives with Remote I/O capabilities, facilitating seamless integration with various control systems like PLC5, SLC500, and Logix platforms. This adapter leverages the traditional Remote I/O protocol, supporting communication speeds of up to 230.4 Kbps, and enables drives to exchange critical operational data such as speed and frequency with connected devices, including HMIs and SCADA systems. Operating efficiently within temperatures ranging from -10 to 50 °C, the compact 20-COMM-R draws a minimal 250 mA at 5V DC from the host drive, ensuring reliable connectivity in non-corrosive environments.Technical specifications for 20-COMM-R Part Number/Catalog No. 20-COMM-R Brand Allen-Bradley Manufacturer Rockwell Automation Description Remote I/O and Data Highway (DH+) communication adapter Communication Port One (1) RIO / DH+ 3 wire Terminal strip Communication Protocol RIO / DH+
