Direct measuring or through current transformer. Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function Ordering Key can be used to avoid relay operation when not desired (maintenance, transitions). The LED's indicate the state of the alarm and the output relay. Through the built-in shunt it is possible to monitor loads up to 10 A AC/DC.

Example 1 (connection between terminals Z1, Y1 or 8, 9 - latching function enabled) Example 2 (Stardard CT) (no connection between terminals Z1, Y1 or 8, 9 - latch function disabled) The relay operates and latches in operating position when the measured value exceeds (or drops below) the set level for more than the set delay time. Provided that the current has dropped below (or has exceeded) the set point (see hysteresis setting), the relay releases when the interconnection between terminals Z1, Y1 or 8, 9 is interrupted or the power supply is interrupted as well. The red LED flashes until the delay time has expired or the measured value comes back to a non-alarm value (see hysteresis setting). The relay operates when the measured value exceeds (or drops below) the set level for more than the set delay time. It releases when the current drops below (or exceeds) the set level (see hysteresis setting) or when power supply is interrupted. Note When the inhibit contact is opened, if the input signal is already in alarm position, the delay time needs to elapse before relay activation.
