Morningstar Relay Driver - Logic Module Accessory

Written March 07, 2008

Exceeded my expectations

Calling this product a relay driver is, in my opinion, a mistake. The name implies that it simply amplifies a weak signal in order to power a relay. The device is much more than that. It should be called a programmable logic module, or perhaps a 4-channel programmable voltage controlled switch. Programming the device is easy to do using MSView software (included). No special programming or computer skills are necessary. Setup parameters include features like delays that can be set in order to prevent false triggering. Minimum and maximum relay on/off time periods can also be set. The MSView software is available for download from the Morningstar website, allowing the potential buyer to learn about the product before buying it. My only complaint is that the hardware and software user's manuals are short on details. To learn about the product, you really have to try it. If you do, you'll be pleased.
