Latch Unlatch Circuit at David Taggart blog

Latch Unlatch Circuit. An example of a latch circuit is shown in figure 1.18.  — example for latching circuit: When the input a contacts close, there is an output. Most plc latch/unlatch (set/reset) instructions are retentive, meaning if an output was energized when a power failure occurs, then when power is restored, the plc will put that output back in an energized state. However, when there is an output, another set of contacts associated with the output closes. A latch in ladder logic uses one instruction to latch, and a second instruction to unlatch , as shown in figure 1 below. When x400 is momentarily closed, it energizes y430 and closes its contacts. How latches and unlatches work in the controllogix processors, and some dangers to be aware of if attempting to use latching on prime movers.  — — ricky bryce. learn how to use latching and unlatching in plc programming through example problems in this educational blog.  — an important distinction between the 2 methods in regards to potential safety problems:
