Overview
The Indramat RMI-01 (part number 226981) is a compact input module engineered for use with Indramat and Rexroth servo drive control systems. This unit handles discrete 24VDC input signals and serves as a critical interface between external sensors, buttons, and limit switches and the main drive controller. The RMI-01 is widely deployed in industrial motion control, CNC machinery, and factory automation equipment where reliable signal acquisition is essential.
Key Features
- 24VDC input logic level—compatible with standard industrial control signals
- Compact modular design for integration with Indramat DKC, TDM, and legacy drive controllers
- Robust signal conditioning for noisy industrial environments
- Drop-in replacement for legacy Indramat control installations
- Proven reliability in CNC machine tools, metal forming, and automation systems
