Description

Steel Interface Box 4x3x1.25 DB9 Input DB25 Control RD Signal Breakout Module

Signal breakout and interface module for routing receive data (RD) signals between serial and control systems. Benchtop unit with steel enclosure housing dual D-Sub connectors for signal distribution and protocol conversion in telecom and industrial applications.

Specifications & What's Included

  • Dimensions: 4 x 3 x 1.25 inches
  • Input: DB9 Female (9-pin D-Sub)
  • Control: DB25 Female (25-pin D-Sub)
  • Signal: RD (Receive Data)
  • Enclosure: Steel
  • Form Factor: Benchtop/Standalone
  • Unit only; no cables included

Applications

Used in legacy telecom, data acquisition, and industrial control systems requiring serial signal routing. Typically deployed for interfacing between modems, multiplexers, and control terminals where DB9 and DB25 connectors are standard. Common in older PBX systems, test equipment configurations, and RS-232 network installations where signal breakout and distribution between different connector types is necessary.

Condition: Used
This steel interface box has been inspected and is in good condition. The enclosure shows light surface scuffing and minor handling marks consistent with normal prior use, but remains structurally sound with no dents or damage. Both connectors — the DB9 input and the DB25 control — are present and appear clean and intact. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
