Relay opening contact

It implements the boolean AND-NOT operation for the input of the block and the value supplied to the corresponding control winding of the relay. In other words, if a logical one is supplied to the input to the block, an inverse value for the relay control windingwill be formed at the output, i.e. the relay opens. If a logic zero is applied to the input to the block, a logic zero will always be formed at the output, regardless of the state of the relay. To view the structure of the algorithm, right-click the block and select the item Actions → Enter to the submodel. The signal transmission from the control winding of the relay is implemented using the block From memory.
