EM-21C is a rugged industrial MP3 player designed for the most demanding jobs. Much like a CD player playing sound tracks from a CD, EM-21C 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-21C features a built-in 6W x 2 power amplifier which can be optionally turned off during standby to save power (battery life). A line level output is also available for external amplification if needed. Audio playback can be triggered with a variety of methods such as push buttons, motion/alarm sensors and PLCs.

EM-21C 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 file at intervals configurable from 1 to 99 minutes.

Housed in a compact yet rugged metal case, EM-21C 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.

Zero Watt Standby Power
When configured in the battery mode, EM-21C shuts down completely while idle and draws zero watt of power. This feature is particularly beneficial for those battery operated applications where the usage is infrequent and the battery is drained mostly while idle.
