Brief: Ever wondered how a high-density relay output module can streamline your industrial control systems? This video provides a detailed walkthrough of the Allen-Bradley 1756-OW16I, showcasing its 16 isolated channels, wide voltage switching capabilities, and practical integration into machine control and process automation applications.
Related Product Features:
  • 16 isolated Form A (SPST-NO) relay outputs for flexible load switching.
  • Individual channel isolation rated at 250V AC for enhanced safety and reliability.
  • Wide voltage range switching from 5-250V AC/DC at 2A per channel.
  • High-density design with 16 channels in a single-slot ControlLogix footprint.
  • Individual green LED status indicators for each output channel for easy monitoring.
  • Removable spring clamp terminal blocks for simplified wiring and maintenance.
  • Industrial-grade construction with certifications including cULus, ATEX, and CE.
  • Long mechanical life of 10 million operations for demanding applications.
FAQs:
  • What types of loads can the 1756-OW16I module switch?
    The module can switch various AC/DC loads including resistive loads up to 2A @ 250V, inductive loads (0.5A AC/0.25A DC), lamp loads (0.5A), and motor loads (0.5A), making it suitable for contactors, solenoids, motors, and indicators.
  • Is external protection required when switching inductive loads?
    Yes, appropriate suppression such as RC snubbers, varistors, MOVs, or diodes is recommended for inductive loads to protect relay contacts and extend operational life, especially given the inrush current limitations.
  • What system requirements are needed to use the 1756-OW16I module?
    The module requires a ControlLogix chassis (4, 7, 10, 13, or 17-slot) and a ControlLogix processor for operation. It is also compatible with CompactLogix systems when used with a 1769 adapter.
