Phoenix Contact 2959586 UM 25-D15SUB/B/FRONT/Q interface module content_copy

The interface module UM 25-D15SUB/B/FRONT/Q from Phoenix Contact is a miniature connector for use in industrial systems. It belongs to the VARIOFACE SLIM-LINE product series and serves as an interface for signal transmission between devices. The module is equipped with a D-Subminiature female connector strip with 15 poles and features a screw connection for secure wiring. Mounting is done transversely on a standard rail profile NS 35/7,5, enabling flexible integration into existing enclosures.

Applications
This module is designed for use in industrial control and automation systems where reliable and compact signal transmission is required. It is particularly suitable for applications where multiple signals are transmitted via a standardized D-Sub interface, for example in machine and plant engineering. Use in enclosures with standard rail profiles enables standardized mounting and simplifies maintenance and expansion of the system.

Functions and Equipment in Detail
The interface module features a D-Subminiature female connector strip with 15 contacts, designed for connection to corresponding connectors. The contacts are connected via a screw terminal, ensuring a mechanically stable and electrically reliable connection. The connector strip is designed for transverse mounting on an NS 35/7,5 rail, enabling space-saving installation in enclosures. The housing is compact and follows the Slim-Line design of the VARIOFACE series, allowing seamless integration into existing systems.

Technology Explained Simply
The D-Subminiature female connector strip is a standard in industrial electronics, enabling the transmission of multiple signals through a single connector system. The 15-pole configuration provides sufficient contacts for many applications, such as serial interfaces, control and status signals. The screw connection ensures a secure mechanical connection of the wires, which remains stable even under vibration and mechanical stress. Mounting on the NS 35/7,5 rail is a standard in enclosure technology and enables modular and standardized installation.

Compatibility and Accessories
The module is compatible with pre-wired cables also configured in D-Subminiature form with 15 poles. Suitable cables include pre-wired cables of various lengths (e.g. 0.5 m, 1.5 m, 3.0 m, 4.0 m, 6.0 m) and different versions, such as with or without wire end ferrules. These cables enable direct connection between the interface module and other devices or connectors. The cables are designed for industrial environments and support reliable signal transmission.

Mounting and Installation
Mounting is done by securing the module transversely onto an NS 35/7,5 rail. No additional mounting aids are required, as the rail itself provides the mounting. Wiring is done via the integrated screw terminal, connecting the wires according to the terminal assignment. Installation is simple and requires no special tools, except a screwdriver for securing the wires.

Advantages in Operation
The interface module provides a compact and robust solution for signal transmission in industrial systems. The use of the D-Subminiature female connector strip ensures a standardized interface compatible with many devices. The screw connection ensures a mechanically stable and electrically reliable connection, even under industrial conditions. Mounting on the NS 35/7,5 rail enables modular and standardized installation, simplifying maintenance and expansion of the system. The Slim-Line housing saves space in the enclosure and integrates well into existing systems.
