Information About 20-COMM-R
The 20-COMM-R is an optional interface module that extends a PowerFlex drive’s communication capability to legacy RIO and DH+ networks commonly used with PLC-5, SLC 500, and early Logix platforms. The adapter enables read/write access to drive parameters, command data, status information, and diagnostic values. Its 3-wire terminal strip supports the Belden 9463 cable used in RIO networks with daisy-chain topology. Designed to meet industrial environmental standards, the adapter operates within a wide temperature range and includes LED status indicators to assist with diagnostics. Typical applications include drive integration into existing RIO infrastructure, SCADA systems, and HMI-connected automation networks.
Key Features
- Remote I/O / DH+ Connectivity: Provides communications for legacy Allen-Bradley control systems.
- Multiple Data Rates: Supports 57.6 kbps, 115.2 kbps, and 230.4 kbps operation.
- Direct Drive Integration: Installs into the communication slot of PowerFlex 70/700 drives.
- Drive-Powered Module: Consumes 250 mA at 5 VDC supplied by the host drive.
- Diagnostic Indicators: Includes status LEDs for network and module health.
- Robust Environmental Ratings: Operates from –10 to 50 °C with 5–95% non-condensing humidity.
- RIO Daisy-Chain Support: Compatible with 3-wire RIO connections using Belden 9463 cable.
- Regulatory Compliance: Meets UL508C, CSA, and EN61800-3 industrial standards.
The 20-COMM-R delivers the reliability and precision required for integrating PowerFlex drives into Remote I/O and DH+ automation networks.
