GE IC3645LXCD1 16-Channel Relay Output Module

Technical Specifications

• Output Configuration:
  • 16 relay outputs (NO contacts), divided into 2 groups of 8 channels each.
  • Contact Rating: 250 V AC / 30 V DC voltage, 5 A continuous current (10 A peak for short durations).
• Response Time:
  • Instruction response time < 10 ms, ensuring rapid execution of control commands.
• Communication:
  • Connects to Series 90-70 controllers via backplane bus, requiring no additional configuration.
• Power Requirements:
  • Logic Power: 5 V DC ±5% (supplied by the Series 90-70 chassis).
  • Load Power: 120–250 V AC or 24–30 V DC per group (independent power supplies for each group).
• Environmental Tolerance:
  • Operating Temperature: 0°C to 60°C.
  • Storage Temperature: -40°C to 85°C.
  • Humidity: 5% to 95% (non-condensing).
• Certifications:
  • UL 508 (Industrial Control Equipment), CSA C22.2 No. 142 (Canadian Safety Standard), CE, and RoHS compliance.

Functional Features

• High Reliability:
  • Silver-alloy contacts with antioxidant treatment ensure a lifespan of up to 100,000 switching cycles, reducing downtime in high-frequency applications.
• Fault Protection:
  • Built-in reverse-flow diodes suppress voltage spikes from inductive loads (e.g., motors, solenoids).
  • Overcurrent protection automatically disconnects overloaded channels to prevent damage.
• Redundant Architecture:
  • Dual-group independent power supplies allow one group to remain operational if the other fails, enhancing system stability.
• Real-Time Monitoring:
  • 16 dual-color LEDs (green/red) indicate channel status (closed/fault), while 2 group power LEDs show supply health.
  • Fault signals (e.g., overload, power loss) are transmitted to the controller for diagnostics.
• Industrial-Grade Design:
  • 2500 V RMS insulation between relay and logic circuits resists electromagnetic interference (EMI) in harsh environments.

Application Scenarios

• Automotive Manufacturing:
  • Controls robotic arms, welding equipment, and conveyor systems in assembly lines, ensuring precise timing for safety-critical operations.
• Metallurgical Processing:
  • Manages high-frequency actuators in rolling mills and cooling systems, where reliable switching is essential for process continuity.
• Food and Beverage Production:
  • Drives valves, pumps, and packaging machinery, maintaining hygiene standards with sealed relay contacts.
• Water Treatment:
  • Regulates chemical dosing pumps and flow control valves, ensuring accurate dosing and system stability.
• Energy Management:
  • Monitors and controls power distribution equipment in substations, reducing outage risks through redundant outputs.

Key Advantages

• Longevity: Silver-alloy contacts outlast standard copper alternatives, minimizing replacement costs.
• Stability: Dual-group power supplies and fault isolation prevent single-point failures from disrupting entire systems.
• Diagnostics: LED indicators and controller feedback simplify troubleshooting, cutting maintenance time by up to 80%.
• Compatibility: Seamlessly integrates with Series 90-70 PLCs and supports both AC/DC loads, reducing inventory complexity.
