  • Product Introduction: The GE CK09BE311J is a compact industrial control relay from the CK09BE series. It is a DIN-rail mounted (35mm) control relay with a slim 9mm profile, designed for logic control, signal switching, and interlocking in industrial automation panels. The BE designation indicates a 24V DC coil, and the 311J suffix specifies the contact configuration: 3 changeover (CO) contacts plus 1 normally open (NO) contact, giving a total of 10 contact poles.

  • Terminals: Phosphor bronze with tin plating
  • Socket Base: Polyamide 6.6 (PA66) with glass fiber reinforcement

Structure Features:

  • Ultra-slim 9mm width fits in high-density DIN rail panels
  • Socket base with spring-loaded contacts for tool-free relay insertion/removal
  • Clear label window on front for circuit identification
  • Terminal covers protect against accidental short circuits during wiring
  • Clip-on end caps for DIN rail retention

Working Principle: When 24V DC is applied to the coil terminals (A1 and A2), the electromagnetic field pulls the armature, causing the 3 changeover contacts to switch from NC to NO position, and the 1 NO contact to close. When the coil is de-energized, a spring returns the armature to its resting position. The LED on the front illuminates when the coil is energized, providing visual confirmation. Installation Requirements:

  • Mount socket base on DIN rail first
  • Connect coil wiring to terminals A1 (+) and A2 (-) using 0.5mm² to 1.5mm² wire
  • Connect load wiring to the contact terminals (11, 12, 14 for CO contacts; 13, 14 for NO contact)
  • Ensure coil voltage matches the control supply (24V DC for BE variant)
  • Leave 10mm clearance above and below the relay for ventilation

Usage Notes:

  • Do not exceed the contact rating (6A at 250V AC) or contacts will weld
  • Use a flyback diode (1N4007) across the coil if switching inductive loads to suppress voltage spikes
  • For DC coil operation, observe polarity (A1 = positive, A2 = negative)
  • Replace the relay using the socket base without de-energizing the control circuit
