Series SYS-800 Relays


The SYS-800 induction relay utilizes the liquid as an electrical conductor to complete the secondary circuit between the upper and lower electrodes. Thus, when the liquid contacts the upper electrode, the resulting fl ow of current in this circuit sets up a bucking action in the lower bar of the core.

This action tends to divert lines of magnetic force to the core legs and sets up an attraction that pulls the armature in to contact with the legs. This armature movement closes the electrode and load contacts.

The flow of current through the low energy secondary circuit is very small and varies with the voltage of the secondary coil. The secondary coil is selected to operate over the resistance of the liquid being controlled. Accordingly, since there is a wide range of secondary coils from which to choose from.
