DL444 analogue D-type I/O module

The DL444 D-type I/O module provides a high density analogue I/Os in a compact

module. The module incorporates current limited (5mA maximum) and short circuit

protected LED outputs, which are independently driven to protect the module from

external wiring faults. Status of the module’s LEDs can be monitored remotely.

The DL444 D-type I/O module has eight channels of premium mic preamps and eight

channels of premium output stage via two standard 25-way, D-type connectors. The

mic preamp is in 2.5dB steps, which is similar to the Midas DL431 Mic Splitter, but

without the splitting capability.

Each of the eight inputs has a red LED to show the on/off status of its +48V phantom

voltage. Similarly, each output has an LED to show whether its mute is on/off. A third

25-way D-type connector lets you view the status of all 16 LEDs remotely.
