Reliable Control Modules We have developed a lock-out automated billing system using the SeaLevel 110e. The system is PHP-MySQL based, controlling access to high dollar electron microscopes and other analytical equipment. The system was also designed to generate billing automatically. To provide the control, we needed a device that was affordable and easy to integrate into the system. The 110e was our choice due to the device size and the price. Our layout here was such that controlling four instruments with a single 110e unit was perfect. The small size of the 110e made it easy to design a standard enclosure to protect it from tampering. After approximately 8 months of service the 110e control modules have proven reliable. Currently we have 8 in service as part of our system. In some cases we are able to control an instrument directly without an external relay. Where external relays are required we are using the 110e to switch either specially designed VGA mechanical relays or solid state relays that that switch power. Overall we are very satisfied with the SeaLevel 110e.
