EM-21C QuikWave Audio Player
Stereo MP3, near CD quality
Trigger Input: 1
Relay Output: 0
Serial Port: 0
Input Voltage: 12 VDC
Output Power: 6W x 2
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 to play when trigger is applied or removed.
Allow playback to be interruptible or not.
Play once or loop while trigger is applied.
Automatically play a file at intervals.
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
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.

Power Amplifier AMP-1502HV
AMP-1502HV is a high efficiency class D power amplifier with a
maximum output of 15W per channel in stereo mode, or 55W in BTL
HVTR1 bridges between low impedance and high voltage audio
devices so that low impedance amplifiers can drive high voltage
speakers, and vice versa.
Digital Switch Timer TMR-08
TMR-08 is a 7-day programmable switch timer with 8 internal relays
for triggering QuikWave audio players at preset times of the day,
once or multiple times a day and in any order.
