The relay releases when the voltage drops min. 10% below set point (see hysteresis) or when power supply is interrupted. Example 2 DC voltage metering latching (AC power supply) The relay operates and remains in operating position when the actual voltage reaches set point. Provided that the voltage has dropped min. 10% below the set point (see hysteresis) the relay will release when the interconnection between pins 8 and 9 is interrupted. The relay also releases when power supply is interrupted. Example 3 AC or DC metering (DC power supply) Please note that pins 7 and 10 are internally connected at DC power supply. No current must pass through this internal connection. 2 SJ 185 The SJ 185 measures the average of a sinusoidal voltage (input). The set point, calibrated to rms-value, is set on built-in potentiometer. Example 1 AC voltage metering (AC power supply The relay operates when the voltage reaches set point. The relay releases again when the voltage has dropped min. 10% below the set point (see hysteresis), or when power supply is interrupted. Example 2 AC voltage metering latching (AC Power supply) The relay operates and remains in operating position when the voltage reaches set point. Provided that the voltage has dropped min. 10% below set point (see hysteresis) the relay releases when the interconnection between pins 8 and 9 is interrupted. The relay also releases when power supply is interupted. Example 3 AC or DC metering (DC power supply) Please note that pins 7 and 10 are internally connected at DC power supply. No current must pass through this internal connection.

Resistor limits are 470 k/ 3k (0.25 W). The hysteresis increases by decreasing resistance.
