1. Product Title
Delem DM-102VA – CNC Press Brake Distributed I/O Module
2. Product Overview
The DM-102VA is a specialized distributed I/O module designed by Delem, a global leader in CNC solutions for sheet metal machines. This module serves as a critical interface component within the Delem DA-series control architecture, specifically tailored for hydraulic press brake applications. Its primary function is to manage the complex analog and digital signals required for precise axis control and valve positioning.
The DM-102VA solves the industrial challenge of wiring complexity and signal latency by allowing for decentralized control near the machine’s hydraulic manifold. It handles high-speed analog outputs for proportional valve control and monitors feedback from encoders or linear scales. By offloading these localized tasks from the main CNC unit, the DM-102VA ensures smoother ram movement, higher bending accuracy, and improved diagnostic capabilities for the machine operator.

4. Key Features & Benefits
- High-Speed Bus Integration: The DM-102VA utilizes Delem’s proprietary High-Speed Bus (HSB), ensuring real-time synchronization between the CNC controller and the hydraulic actuators for perfect bending results.
- Proportional Valve Support: Specifically optimized for the “VA” (Valve/Analog) requirements, providing the necessary current and voltage stability to drive complex hydraulic valves with high repeatability.
- Reduced Cabinet Wiring: As a distributed module, the DM-102VA allows for shorter cable runs to sensors and valves, which minimizes electromagnetic interference (EMI) and simplifies machine troubleshooting.
