Safety and hazard information
Please note that electrotechnical work may only be carried out by qualified electricians or under their guidance and supervision. Observe any deviating country-specific electrical installation standards and regulations and seek advice from a local electrician.In addition, observe more current safety instructions and regulations for the products on the manufacturer's side or the product descriptions and installation instructions on the manufacturer's side.

Devices with a connected load of > 380V/400V require a heavy current connection and may only be connected by an approved electrical company. Devices with a power rating > 12kW require the approval of your grid operator (Germany, other countries may differ).

Frequency monitoring relay 20...60Hz AA9837.11 20-60HZ – Dold – 0012799 – 4030641127992: Frequency relay 230V AA9837.11 20-60HZ Design of the electrical connection screw connection, rated control supply voltage Us at AC 50 Hz 230 ... 230V, rated control supply voltage Us at AC 60 Hz 230 ... 230V, voltage type for actuation AC, rated voltage 230 ... 230V, Response value for frequency 20 ... 60Hz, number of contacts as normally closed 0, number of contacts as normally open 0, number of contacts as changeover 1, width 45mm, height 77mm, depth 127mm, The frequency relay works according to the principle of frequency comparison, whereby the Measuring frequency is compared with a frequency generated in the device that can be changed using the adjustment knob. When a switching bridge is connected between terminals X1 - X2, the output relay drops out when the measuring frequency is greater than the set frequency. The relay picks up again when the measuring frequency is smaller than the set frequency x hysteresis factor (function diagram). When a switching bridge is connected between terminals X2 - X3, the relay is activated when the measuring frequency is greater than the set frequency. The relay drops out again when the measuring frequency is smaller than the set frequency x hysteresis factor. The presence of the measuring voltage is indicated by a light-emitting diode, whereby low frequencies can be recognized by the flashing rhythm. Another LED shows the switching status of the output relay
