EM18A is a rugged industrial WAV player designed for the most demanding jobs. Much like a CD player playing sound tracks from a CD, EM18A 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 44.1KHz. Although the sound quality is not as good as our
MP3 players, it is close to AM radio.
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, EM18A features a built-in energy saving class D power amplifier with minimum heat dissipation. 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. Keypads and other custom interfaces are available by special request.
EM18A 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.
- Start/pause/resume/stop the sound via the serial port.
Housed in a compact yet rugged metal case, EM18A 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.
Automatic Time-Triggered Audio Playback
Automatic time-triggered audio playback is possible by controlling the player with an optional TMR-08 Weekly Event Timer. Each weekday may have a different program of events.
Remote File Management
When equipped with the QuikWave Remote File Management Kit the sound files can be remotely managed via wired or wireless network.
