The SoundBytes CTC Bell is a simple, fully self-contained sound module that plays a single stroke bell.  We recorded the bell from a vintage Union Switch and Signal model 506 CTC console, so it sounds like the real deal!  Our friends at Iowa Scaled burned the recording into their SoundBytes sound and speaker module.  The SoundBytes modules work great with our Approach Indicator Controller but can be used with many circuits.  

Power is 5-24 VDC regulated and the control line should be grounded (also should not see more than 3.3V) by an open collector or drain or a dry contact to ground.

We are a dealer of IAScaled products so contact us if you want to purchase a bundled solution including their fine line of model railroad electronics, this may be of special interest to our international customers who are looking to avoid multiple shipping charges!
