Allen-Bradley 1746-OW8 Digital Contact Output Module

Allen-Bradley 1746-OW8 Digital Contact Output Module

Core Technical Specifications

• Brand & Model: This is a genuine Allen-Bradley module, catalog number 1746-OW8.
• Module Type: It is a Digital Contact (Relay) Output Module for the SLC 500 platform.
• Output Configuration: It provides 8 Normally Open (N.O.) relay contacts.
• Operating Voltage: Outputs switch loads from 5-125V DC or 5-265V AC.
• Output Grouping: Relays are split into 2 groups of 4, each with a separate common.
• Output Current (AC): Each point handles up to 1.5 Amps at 120V AC.
• Output Current (DC): Each point handles up to 1.2 Amps at 24V DC.
• Switching Speed: Maximum signal delay is 10 ms for both ON and OFF states.
• Backplane Current: Draws 85-90 mA (5V DC) from the SLC 500 backplane.
• Thermal Dissipation: Maximum heat output is a low 3.7 Watts.

Design & Application Features

• The 1746-OW8 features two independent output groups. This allows operation with different voltage types (AC/DC) simultaneously.
• Its dry contact design provides full electrical isolation between the PLC and the load circuits.
• Using this module eliminates the need for interposing relays, saving cost and panel space.
• We recommend installing external surge suppression on each channel to maximize relay life.
• It is certified for use in Class 1, Division 2 hazardous locations and industrial environments.

Frequently Asked Questions (FAQ)

• Q: Is this module new and authentic Allen-Bradley?
  A: Yes, we supply only brand new, genuine Allen-Bradley products.
• Q: What is the benefit of the two output groups?
  A: The two groups allow you to separate different load types or voltages (e.g., AC in one group, DC in the other) for safer and more flexible control.
• Q: Can I use this module in a remote I/O rack?
  A: Absolutely. The 1746-OW8 is fully compatible with SLC 500 remote I/O chassis.
• Q: What is the maximum load current per output?
  A: Key ratings are 1.5A at 120V AC and 1.2A at 24V DC.
• Q: What is your return and shipping policy?
  A: We offer a 30-day return policy and ship globally via major couriers within 5 business days.
