Programmable Relays Solve Complex Applications

Author: John Grocke, Published on Aug 05, 2013

Many times integrators are presented with complex applications, such as machine interface, mantraps, lighting control, or complex timing scenarios, that cannot be easily accomplished with standard access control functions or IP camera inputs and outputs. Often these problems are solved with great difficulty, using a box full of "ice cube" relays, timers and counters with a nest of wiring or an expensive and complex programmable logic controller (PLC). A simpler and more economical solution is to use a programmable relay, as pictured below:
