Compatible Terminal Bases for the 1794-OA16

• The 1794-OA16 works with multiple terminal bases. Use these bases to mount and terminate signal wires.
• Compatible bases include: 1794-TBN, 1794-TBNF, 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TBKD, 1794-TBNK, 1794-TBNFK, 1794-TB3K, and 1794-TB3SK.
• When using the 1794-TBN base, you will need auxiliary terminal blocks. These blocks connect the 120 VAC common voltage source for individual channels.
• The 1794-TBNF base provides built-in fusing for each output. This simplifies protection for your AC loads.

Environmental and Operating Limits

• Operating Temperature: 0 to 55°C (32 to 131°F) with 5-95% non-condensing humidity.
• Storage Temperature: -40 to 85°C (-40 to 185°F).
• Vibration Resistance: 5g at 10 to 500 Hz.
• Operating Shock: 30 g; Non-operating shock: 50 g.
• ESD Immunity: 8 kV air discharge.
• Mounting: DIN rail (open-type enclosure).

Frequently Asked Questions (FAQ)

• Q: What is the condition of the 1794-OA16 module?
  A: We supply only brand-new, original Allen-Bradley units. Each module comes from factory-sealed stock.
• Q: Do you have this module in stock?
  A: Yes, we maintain ready inventory for the 1794-OA16. We can ship most orders immediately.
• Q: What is your return policy?
  A: We accept returns within 30 days of delivery. Items must remain unused and in original packaging.
• Q: Does the 1794-OA16 have internal fusing per channel?
  A: No. The module has one internal 2.5A fuse for overall protection. For per-channel fusing, use the 1794-TBNF terminal base.
• Q: Can I use this module with a 24 VDC load?
  A: No. The 1794-OA16 only switches AC loads from 74 to 132 VAC. Do not connect DC loads.
• Q: What is the output delay time?
  A: The maximum output signal delay equals 1/2 cycle for both OFF-to-ON and ON-to-OFF transitions.
• Q: Is there isolation between output channels?
  A: No. The 1794-OA16 channels are non-isolated from each other. The module also provides no isolation between outputs and the customer power source.
