Description

Technical Specifications:

  • Channels: 8 digital outputs
  • Output Type: Relay (SPDT, changeover contact)
  • Rated Load (Resistive): 250 V AC / 2 A, 30 V DC / 2 A
  • Rated Load (Inductive): 250 V AC / 1 A (cos φ = 0.4), 30 V DC / 1 A (L/R = 7 ms)
  • Contact Material: AgSnO₂ (silver tin oxide)
  • Mechanical Life: 10,000,000 operations
  • Electrical Life: 100,000 operations (at rated load)
  • Switching Time: 5 ms (typ.), 10 ms (max)
  • Optical Isolation: 500 V DC (channel-to-channel, channel-to-bus)
  • Power Supply: 24 V DC (from CD3 backplane)
  • Power Consumption: 1.2 W (max, all relays energized)
  • Communication: Internal bus (CD3 proprietary, 1 Mbps)
  • Protection Class: IP20
  • Operating Temperature: 0°C to +55°C
  • Storage Temperature: -25°C to +70°C
  • Dimensions: 120 x 90 x 25 mm (W x H x D)
  • Mounting: DIN rail (35 mm) or direct screw mounting
  • Certifications: CE, UL 508, RoHS

Functional Features:

  • LED status indicator per channel (green = relay closed, off = relay open)
  • Flyback diode protection for relay coil (internal)
  • Free-wheeling diode per channel (for inductive load suppression)
  • Status feedback via internal bus (contact state monitoring)

Material Composition:

  • Housing: ABS plastic, UL94 V-0
  • Terminals: Pluggable screw terminals, 1.5 mm² max
  • Relay: Sealed electromagnetic relay, hermetically sealed contacts
  • PCB: FR-4, double-sided

Structural Features:

  • 1 module width, DIN rail clip included
  • Front labeling with channel numbers and NO/NC indicators
  • Bus connector at rear for CD3 backplane

Applicable Industries:
Conveyor motors, solenoid valves, indicator lights, alarm sirens, pump control

Installation Requirements:

  • Must be installed in CD3 controller rack or backplane
  • Wire gauge: 0.5–1.5 mm² for output signals
  • Inductive loads require external RC snubber (recommended for >0.5 A inductive)
  • Max 8 modules per CD3 rack

Usage Notes:

  • Relay contact rating must not be exceeded under any condition
  • Do not switch capacitive loads exceeding 100 µF without external inrush limiter
  • Mechanical life is rated at no-load; electrical life depends on load type
  • Allow 50 ms minimum between switching operations for inductive loads
