Overview
The DB37 breakout board is an industrial-grade interface module designed for reliable signal termination and routing between PLC processors and field devices. This 37-pin D-Sub breakout board serves as a terminal interface, converting D-Sub connector pinouts into individual screw clamp connections for simplified wiring in control panels, motor drives, and automation enclosures.
Key Features
- 37-Pin D-Sub Connector – Full-featured male or female D-Sub configuration with screw locks for secure cable retention
- Screw Clamp Terminal Blocks – Individual wire terminations with clearly labeled positions for rapid identification and reliable connections
- FR-4 PCB Construction – High-quality fiberglass substrate for durability and signal integrity in industrial environments
- Component Integration Holes – PCB features integrated circuit holes between connector and terminal block, allowing direct installation of diodes, resistors, MOVs, or surge protection components
- Space-Efficient Design – Compact module suitable for dense panel layouts and retrofit applications
