Monitoring voltage relay HRN-34

  • SERVES TO CONTROL SUPPLY VOLTAGE FOR APPLIANCES SENSITIVE TO SUPPLY TOLERANCE, PROTECTION OF THE DEVICE AGAINST UNDER/OVER VOLTAGE
  • CONTROLLING OF SUPPLY VOLTAGE FOR APPLIANCES SENSITIVE TO SUPPLY TOLERANCE.
  • SAME DESING LIKE HRN-33, BUT THE VOLTAGE RANGE OF THE MONITORED VOLTAGE IS PREDETERMINED FOR MONITORING THE BATTERY CIRCUITS (12, 24 V).
  • DISCONNECT THE LOAD WHEN THE VOLTAGE DROPS OR THE BATTERY IS LOW.
  • SUPPLY FROM MONITORED VOLTAGE (MONITORS LEVEL OF ITS OWN SUPPLY).
  • ADJUSTABLE TIME DELAY FOR ALL TYPES IS 0 – 10 S (TO ELIMINATE SHORT VOLTAGE DROPS OR PEAKS).
  • VOLTAGE UMIN ADJUSTED AS % OF UMAX.
  • 1-PHASE DESIGN.
Categories: , , , ,

• Single-function and single-time relay with fi ne time setting by a
potentiometer (within the frames of a particular time range).
• Suitable for applications where function and time requirements are
known.
• Time switch, possible to be used for pump delay after switching
heating off , switching of fans.
• Choice of 3 functions:
1) ZR – Delay ON
2) ZN -Delay OFF
3) BL – Repeat Cycle
• Functions can be controlled by supply voltage or time scale control
input
• Choice of 6 time ranges: (0.1 s – 1 s / 1 s – 10 s / 6 s – 60 s / 1 min – 10 min /
6 min – 60 min / 1 h – 10 hrs)
• Universal voltage range AC/DC 12 – 240 V or AC 230 V.
• Output contact: CRM-81J: 1x changeover/ SPDT 16 A
CRM-83J: 3x changeover/ 3PDT 8 A.
• Red LED output indicator.
• 1-MODULE, DIN rail mounting
