Allen-Bradley 1746-OW16 SLC 500 Relay Output Module | 16-Point

Description

Allen-Bradley 1746-OW16 Relay Output Module

The Allen-Bradley 1746-OW16 provides ultimate flexibility for mixed voltage applications in SLC 500 systems. This 16-channel relay output module handles both AC and DC voltages simultaneously across two isolated groups, eliminating the need for interposing relays and simplifying your control panel design.

Frequently Asked Questions (FAQ)

• Q: Can I mix AC and DC voltages on the same module?
  A: Yes, the two isolated groups allow one group to run AC voltages while the other runs DC voltages simultaneously.
• Q: What surge suppression do you recommend for this module?
  A: We recommend installing external surge suppression devices on each channel to protect the relay contacts and extend module life.
• Q: What is the maximum continuous current per module?
  A: The module can handle 16A continuous current total, but ensure you do not exceed 1440VA total power.
• Q: How often should I inspect the module for chemical damage?
  A: Perform periodic inspections based on your environment’s chemical exposure levels to maintain sealing integrity.
• Q: Can I use this module for high-inrush inductive loads?
  A: The relay contacts handle 15A make current at 120V AC, making them suitable for many inductive loads with proper surge protection.
