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).
