Allen-Bradley 1746-OAP12 Output Module 120/240VAC

Allen-Bradley 1746-OAP12 High-Current AC Output Module

Core Technical Specifications

• Brand & Model: Allen-Bradley 1746-OAP12
• Module Type: Digital AC Output Module
• Output Channels: 12 channels, arranged in two groups of six with separate fused commons.
• Output Voltage: 120/240 VAC nominal, with a broad operating range of 85 to 265 VAC.
• Frequency: 47 to 63 Hz.
• Output Current: 2.0 Amps per point at 30°C, derating to 1.0 Amp at 60°C.
• Module Current: Maximum 9.0 Amps total at 30°C, derating to 6.0 Amps at 60°C.
• Backplane Current: Draws 0.370 Amps at 5.1V DC from the chassis.
• Response Time: Fast 1 ms ON delay and 11 ms OFF delay for precise control.

Design & Protection Features

• Electronic Fusing: Each group of six outputs is protected by a dedicated 6.3A electronic fuse (SAN-O HQ type).
• Fuse Monitoring: Includes a configurable jumper to enable or disable blown-fuse monitoring for diagnostics.
• High Surge Capacity: Handles surge currents up to 17A per point for 25ms and 35A per common for 10ms.
• Isolated Groups: One output group remains operational even if a fuse blows in the other, improving uptime.
• Low Voltage Drop: Features only 1.2V drop at the full 2.0A load for efficient operation.

Installation & Compatibility

• Controller Compatibility: Designed for use with any SLC 500 series processor.
• Chassis Integration: Occupies a single slot in the 1746 chassis using a Removable Terminal Block (RTB).
• Fault Handling: Note that with SLC5/02 and later processors, a fault routine cannot clear the major fault bit (S:1/13).

Environmental & Durability

• Operating Temperature: Reliably performs in temperatures from 0 to 60°C (32 to 140°F).
• Humidity Rating: 5% to 95% non-condensing relative humidity.
• Robust Construction: Withstands 30G operational shock and 5G vibration (10-500 Hz).

Packaging & Support

• Package Contents: One Allen-Bradley 1746-OAP12 AC Output Module.
• Condition: Brand new, original, and factory sealed.
• Replacement Parts: Fuse kit (Catalog 1746-F9) contains five replacement fuses.
• Stock & Shipping: Available from stock; ships within 5 business days via FedEx, UPS, or DHL.

Frequently Asked Questions (FAQ)

• Q: What makes the 1746-OAP12 a "high-current" module?
  A: The 1746-OAP12 delivers 2.0 Amps per output point at 30°C, which is significantly higher than standard 0.5A or 1.0A modules.
• Q: How are the outputs protected?
  A: Outputs are protected in groups of six by a 6.3A electronic fuse. A replacement fuse kit (1746-F9) is available.
• Q: Can I monitor if a fuse has blown?
  A: Yes, the module has a jumper to enable fuse monitoring. By default, this monitoring is disabled (jumper on pins 2-1).
• Q: What happens if one fuse blows?
  A: Only the group of six outputs associated with that fuse will de-energize. The other group continues normal operation.
• Q: What is your return policy?
  A: We support a 30-day return period for unused products in their original packaging.
