Relay out­put module HE 5826


The relay out­put module HE 5826 con­trols up to four signals from the hig­her-level bus sys­tem and for­wards them via four poten­tial-free chan­geo­ver cont­acts to con­nec­ted sys­tems or instal­la­ti­ons. The out­put logic can be inver­ted indi­vi­du­ally. Com­mu­ni­ca­tion with the bus cou­pler takes place via an asyn­chro­nous serial RS485 con­nec­tion.


The signal sta­tus of the relay out­puts is indi­ca­ted via sta­tus LEDs. The out­puts and the logic area are gal­va­ni­cally iso­la­ted from each other. Module errors and errors in case of over­load, short cir­cuit or miss­ing sup­ply are detec­ted and dis­played.

In the event of a fault, the out­puts change to a pre­viously defi­ned safe sta­tus (Fail Safe).
