Output control and protection device, in particular for programmable automatic controllers |
摘要 |
A device for controlling and protecting outputs against overcurrents, in particular for programmable automatic controllers, comprises for each output channel a protection circuit connected by a single terminal to a power switch and to its control circuit. In the protection circuit a comparator compares with a threshold a voltage imaging the current in the output channel and disabling means are connected to a circuit for forcing the comparator input voltage. A common terminal is therefore used to monitor and to disable the output channel.
