EM-21D is a rugged industrial MP3 player designed for the most demanding
jobs. Much like a CD player playing sound tracks from a CD, EM-21D plays
sound files from an SD/SDHC memory card but without the moving parts to
wear and tear. The player supports the ISO 11172-3 MP3 standard (up to 320
Kbps) and provides better sound quality than other MP3 players supporting
256 kbps or less.
Powered by a single voltage DC power supply,
EM-21D features a high efficiency low heat
class D power amplifier with thermal and
short circuit protection (automatic recovery).
The amp can also be configured as BTL (Bridge
Tied Load) for power boost in mono
applications. A line level output is available for
external amplification if desired.
Audio playback can be triggered with a variety of methods such as keypad
(3x4), push button, motion/alarm sensor and PLC.
EM-21D can be easily configured to work in different operation modes such as:
•
Start the playback when the trigger is applied or removed.
•
Allow the playback to be interruptible by the next trigger or not.
•
Play the sound just once or loop it till the trigger is removed.
•
Automatically play a list of files with user configurable delay time.
•
Up to 10 groups of separate audio files and system configuration.
Housed in a compact yet rugged metal case, EM-21D can be easily secured into
place with the integrated mounting tabs on each side of the unit. Wiring is
done via screw terminals and requires only a small screw driver. The screw
terminals are unpluggable, making it fool-proof to replace the unit in the field
when necessary.
