• Module Type: It is a Digital Contact (Relay) Output Module for the SLC 500.
• Output Configuration: The module provides 16 Normally Open (N.O.) relay contact outputs.
• Operating Voltage: Outputs can switch a wide range from 5-125V DC or 5-265V AC.
• Output Grouping: It has 2 independent groups with 8 outputs and one common terminal each.
• AC Current Rating (120V): Each point handles 1.5 A break current and 15 A make current.
• DC Current Rating (24V): Each point handles 1.2 A break current at 125V DC.
• Signal Delay: Maximum switching time is 10 ms for both ON and OFF states.
• Backplane Current: It draws 170-180 mA from the 5V DC backplane.
• Module Current Limit: Total continuous current must not exceed 16 A to stay within the 1440VA power limit.

Design & Application Features

• The 1746-OW16 acts as a dry contact relay module, providing complete electrical isolation.
• Its two separate output groups allow you to control different voltage types (AC and DC) simultaneously.
• This design removes the need for external interposing relays, saving panel space and cost.
• We recommend installing external surge suppression devices on each channel to protect the relay contacts.
• The module features a removable terminal block (RTB) for quick and easy wiring.

Frequently Asked Questions (FAQ)

• Q: Is this a genuine Allen-Bradley module?
  A: Absolutely. We supply only new, original Allen-Bradley products.
• Q: What does "dry contact" mean for the 1746-OW16?
  A: Dry contact means the relay outputs are isolated. They only switch the user-supplied power (AC or DC), making them very versatile.
• Q: Do you offer a return policy?
  A: Yes, we provide a 30-day return policy for your complete satisfaction.
