Frequently Asked Questions (FAQ)
1. What type of output does the 1769-OB16P provide?
This module provides sixteen (16) sourcing (24VDC) solid-state outputs. It is perfect for controlling solenoids, relays, and indicators.
2. Can I use this module with my MicroLogix 1500 controller?
Yes, the Allen-Bradley 1769-OB16P works as a local I/O expansion module. It connects directly to the MicroLogix 1500 base.
3. Does the 1769-OB16P have fuse protection?
No, it uses integrated electronic protection instead of physical fuses. This protects each channel from shorts and overcurrent automatically.
4. What terminal block does this module require?
You need the 1769-RTB18 removable terminal block for wiring. This terminal block is not included in the module package.
5. What is the maximum current per output point?
Each output point handles 1.0 A at 30°C (86°F). At 60°C (140°F), each point handles 0.5 A. Always derate for higher temperatures.
