EM-2220A is a rugged industrial audio player designed for the most
demanding jobs. Much like a CD player playing sound tracks from a CD, EM-
2220A plays sound files from an SD/SDHC memory card but without the
moving parts to wear and tear. The file format support is 8-bit uncompressed
WAV files with sampling rate up to 22.05KHz. Although the sound quality is not
as good as our MP3 players, it is adequate for most voice playback
applications.
Audio programming for the unit is as simple as copying sound files to the
memory card via a card reader attached to the computer. The type of memory
cards used, the SD/SDHC cards, are most popular and readily available in a
number of capacities to suit different needs. Hundreds of tracks totaling hours
of audio can be stored onto an inexpensive card for instant playback.
Powered by a single voltage DC power supply, EM-2220A has a built-in power
amplifier to drive speakers directly. Audio playback can be triggered with a
variety of mechanisms such as push buttons, motion/alarm sensors and PLCs.
Once triggered, the unit can operate according to user configuation in different
modes such as:
•
Start the playback when the trigger is applied or removed.
•
Allow the playback to be interruptible by another trigger or not.
•
Play the sound just once or loop it till the trigger is removed.
Housed in a compact yet rugged metal case, EM-2220A 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.
