Competitive Advantage

High-Density Analog Intercom Management
The Industronic 341-720-300 12 DAL 03 manages up to 12 analog intercom stations and 48 line inputs/outputs. With input impedance of approx. 5,000 ohms and output impedance of 300 ohms, the 341-720-300 12 DAL 03 ensures accurate AF signal transmission and reception across multiple stations.

Short-Circuit and Overvoltage Protection
Each line output of the 341-720-300 12 DAL 03 is protected against short circuits and overvoltage. With operating peripheral voltage of 48–72 V and max. current per 8 lines at 350 mA, the 341-720-300 12 DAL 03 prevents damage to connected intercom stations and amplifiers.

Galvanic Separation and Signal Isolation
The 341-720-300 12 DAL 03 provides transformers for galvanic separation for each AF channel, isolating transmission lines from control electronics powered at 5 V with 0.3 A current consumption. This ensures the 341-720-300 12 DAL 03 maintains clean signal paths while preventing electrical interference.

Front-Panel Service Access
The 341-720-300 12 DAL 03 includes 2 × 25-pin Sub-D connectors for control lines, 1 × 25-pin Sub-D for AF signals, and 1 RS232 service interface. Hot swapping is supported, allowing technicians to replace or service the 341-720-300 12 DAL 03 without interrupting system operation.

LED Signal Indicators for Monitoring
Each intercom station on the 341-720-300 12 DAL 03 has a green LED to indicate AF signal activity and a red LED for faults. This enables immediate detection and troubleshooting of signal or line issues in industrial intercom systems.

HDLC Interface for DXC Controller Communication
The 341-720-300 12 DAL 03 digitizes incoming AF signals and transmits PCM data through the HDLC interface to the DXC controller, allowing seamless integration and automated control of connected analog intercom stations.
