  • Control AC and DC voltage (switches)
  • A wide range of rated (Urated) controlled voltages (switches);
         - DC from 24 to 240V
         - AC from 24 to 240V
  • Adjustable defeatable threshold to decrease the voltage -30…-5% of Urated
  • Adjustable defeatable threshold to increase the voltage +5…+30% of Urated
  • Fixing actuation delay 0,5s, 2s, 5s, 10s
  • It does not require an additional power supply
  • Width of case is 13mm
 
PURPOSE OF THE RELAY
 Relay control voltage RKN-1M is designed to issue control command when the controlled voltage deviates from the set threshold values. It can be used as over- or undervoltage relay or relay of alarm status control (control two thresholds at the same time, ie, control of the "window"). Power relay is carried out by a controlled voltage, a separate voltage supply is not required.
 
DESIGN OF THE RELAY
 Relay is produced in a plastic case with a unified front connection wires power and switched circuits. Mounting is carried out on a DIN rail  width 35mm (GOST R IEC 60715-2003) or on a smooth surface. To set on a smooth surface, you need to push locks. Terminal design provides robust clamp wires up to 2,5mm2. On the front panel there are: rotary switch of upper threshold «U˃%», rotary switch of lower threshold «U˂%», the green LED "norms.", red LED "accident". On the side surface located DIP- switch to select the rated power voltage (switches 1-4)delay of operation (switches 5-6) and operation diagrams (switches 7-8).
 
OPERATION OF THE RELAY
 The relay provides three modes of operation: mode "window" (voltage control the upper and lower thresholds), mode "maximum voltage relay(control only the upper threshold) and mode "minimal voltage relay(control only the lower threshold). At power to the relay, if the net voltage is in preset range, the built-in relay is turn on (contacts 11-14 closes) after the counting delay operation and lights the green indicator "normal". If the net voltage deviated from the set values, built-in relay switches off on expiry of counting time delay (contacts 11-12 closes and the red indicator  "accident" lights, while the counting time delay will be lit the green indicator "normal", and the red indicator "accident" will be flash). When the controlled voltage returns to normal the relay switches on after the counting delay of operation.
