Description

3DBM Inc 70FMO-DL-1-3-A-1 FM Modulator Module Rackmount 70 MHz RF 105-125V

FM modulator module designed for rackmount integration in broadcast and telecom systems. Operates at 70 MHz RF frequency and accepts modulation input via BNC connectors.

Specifications & What's Included

  • Model: 70FMO-DL-1-3-A-1
  • Frequency: 70 MHz
  • Power Requirements: 105-125 VAC, 60 Hz
  • RF Output: BNC (J5)
  • Modulation Input: BNC (J6)
  • Monitor Output: BNC (J9)
  • Status/Control: DB9 interface with remote calibration, alarm control, and fault monitoring
  • Front Panel: OPERATE/CALIB switches, meter display, ON and FAULT indicators
  • Form Factor: Rackmount module

Applications

FM modulator modules of this type are used in broadcast transmission systems, telecom infrastructure, and RF distribution networks. The 70 MHz intermediate frequency is typical for modular broadcast equipment and cable television headend systems. These modules serve as building blocks in larger rackmount systems for signal processing and frequency conversion.

Condition: Used
This 3DBM Inc 70FMO-DL-1-3-A-1 FM Modulator Module has been inspected and appears to be in good condition. It was pulled from a working environment where it was in active use. The gold-anodized aluminum enclosure shows light surface wear and minor discoloration consistent with normal rack service life. Front panel controls, switches, and indicators are intact. Rear connectors — including the BNC RF OUT, BNC MOD IN, DB9 status port, and power inlet — all appear undamaged. Please view our photo set and contact us if you have any questions.
