Description
The Allen-Bradley 1769-OW8I is a CompactLogix discrete output module designed for industrial control applications. This module features eight individually isolated relay outputs, providing flexibility and protection for various control circuits. As part of the 1769 Compact I/O series, it is engineered for seamless integration with CompactLogix or MicroLogix 1500 controllers, offering reliable switching for both AC and DC loads.
Features
- Eight (8) individually isolated relay outputs for enhanced circuit protection and flexibility.
- Supports a wide operating voltage range, accommodating 5 to 265V AC and 5 to 125V DC.
- Compact form factor suitable for space-constrained control cabinets.
- Designed for use with 1769 Compact I/O systems.
- Normally open relay configuration for standard industrial switching requirements.
Applications
This module is typically used in automation systems requiring the isolation of output signals from the main controller logic. It is ideal for driving external actuators, contactors, or solenoids where electrical isolation between channels is necessary to prevent ground loops or cross-channel interference.
