Working Principle:
When DC 24V is applied to the relay coil, it generates a magnetic field that attracts the armature, causing both sets of changeover contacts to switch state. The normally open contacts close and the normally closed contacts open, completing or breaking the connected circuits. The LED indicator illuminates when the coil is energized, providing visual confirmation of relay status. The mechanical indication window shows the physical position of the contacts. The test button allows manual actuation of the relay for testing and commissioning purposes without applying voltage to the coil.

Installation Requirements:

  • Mount on compatible PGR-2C-E socket
  • Ensure proper socket installation on DIN rail or panel
  • Connect coil terminals to DC 24V control circuit
  • Connect contact terminals to load circuits
  • Verify correct polarity for DC coil
  • Ensure adequate clearance around relay
  • Install in clean, dry environment
  • Follow wiring diagrams for proper connections

Precautions for Use:

  • Verify coil voltage matches DC 24V specification
  • Do not exceed 5A contact load rating
  • Use appropriate socket (PGR-2C-E recommended)
  • Consider adding surge protection modules for inductive loads
  • Regularly verify operation through test button
  • Monitor LED indicator for proper status
  • Keep relay clean and free from contamination
  • Replace if contacts show signs of wear or damage
  • Ensure proper ventilation to prevent overheating
  • Follow proper lockout/tagout procedures during maintenance
