Hi-Fi Audio with Multiple Synchronized Control Outputs
The EM51A supports stereo MP3 audio conforming to the ISO 11172-3 standard with CBR/VBR up to 320 kbps for the best sound quality. After being triggered the system starts to play the animation audio and toggle multiple
control outputs at preset moments. These outputs are typically used to control external electrical/electronic devices such lights, solenoids, motors, valves and etc. When not triggered the system can be configured to play
ambient audio (a different MP3 file) continuously.
Versatile Trigger Methods
The animation can be triggered with push buttons, pressure floor mats,
switch/relay closures, alarm/motion sensors, PLCs and etc. Two trigger inputs are provided (although they trigger the same animation program): one for dry contact closures and the other is opto-isolated. Trigger polarity can be
reversed with a DIP switch setting.
Class D Power Amplifier & Line Out
An internal class D power amplifier is standard on the EM51A. Due to the high efficiency of class D amplifiers external cooling
is usually not necessary. Line level output is also available for feeding external power amplifiers in case more amplification is needed than the internal one can provide.
Removable Flash Card Storage
Audio files are stored on a removable flash card making it easy to change audio contents in the field. The animation program
is, on the other hand, stored in the systemís flash memory (not removable).
Standalone Operation & Easy Installation
The EM51A is totally self-contained in terms of operation. Installation is quick and easy thanks to the detachable screw terminals. No connector is required for wire connection.
Built Tough & Reliable
Built with industrial grade components and housed in rugged metal enclosures, the EM51A will provide years of reliable operation even under the most harsh conditions.
Teach-n-LearnTM Programming Method
The EM51A allows the user to do animation programming with nothing but the controller itself. Built-in push buttons are used to activate outputs and play out
the animation for the controller to learn while the audio is played simultaneously. A DIP switch setting can lock the system and prevent the erasure of the animation program.
