Product Advantages

  • High Channel Density: 32 outputs in a single module reduce panel space and simplify wiring.
  • Flexible Grouping: Outputs are grouped in four banks of 8, allowing different voltage levels or commons within the same module.
  • Robust Isolation: High isolation voltage protects the PLC backplane and logic from field disturbances.
  • Status Indication: Individual LEDs per point provide quick visual diagnostics.
  • Wide Voltage Range: Compatible with various industrial DC control voltages.
  • Reliability: Designed for continuous operation in harsh industrial environments.

Precautions

  • Heat Dissipation: Ensure adequate ventilation around the module, especially when operating near maximum current.
  • Power Supply Limits: Do not exceed the maximum current per point or per bank to avoid damage.
  • Wiring Practices: Use proper wire gauges and secure connections to prevent voltage drop or intermittent operation.
  • Grounding: Follow proper grounding practices to minimize electrical noise and ensure safety.
  • Environmental Compatibility: Avoid exposure to extreme temperatures, humidity, or corrosive atmospheres unless the enclosure is appropriately rated.

Product Applications

  • Manufacturing Automation: Controls actuators, relays, and pilot lights in assembly lines and robotic cells.
  • Process Control: Manages valves, pumps, and alarms in water treatment, chemical processing, and oil & gas industries.
  • Material Handling: Drives conveyor motors, diverters, and sorters in distribution centers.
  • Packaging Machinery: Activates solenoids and cylinders in filling, sealing, and labeling equipment.
  • Building Automation: Interfaces with lighting systems, HVAC controls, and security devices.
