EM-18A is a rugged industrial audio player designed for the most demanding
jobs. Much like a CD player playing sound tracks from a CD, EM-18A 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-18A features a high efficiency low heat
class D power amplifier with thermal and
short circuit protection (automatic recovery). A
line level output is also available for feeding
an external amplifier if desired. Audio
playback can be triggered with a variety of
methods such as push buttons, motion/alarm sensors and PLCs.
EM-18A 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 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-38A 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.
