Overview
The Allen-Bradley 1769-OW19 Series A relay output module is part of the CompactLogix Compact I/O family, designed for expanding the digital output capabilities of CompactLogix and MicroLogix controllers. This relay output module provides individually isolated Form A (normally open) relay outputs for switching both AC and DC loads in diverse industrial control applications. Each channel operates independently at different voltage levels without group restrictions, offering flexible mixed-voltage control.
Key Features
- Individually isolated relay output channels enable independent voltage switching per channel
- Form A (normally open) relay outputs for reliable contact switching
- Wide operating voltage range of 5 – 265VAC and 5 – 125V DC
- Compact DIN rail or panel-mount design for flexible installation
- LED status indicators for real-time diagnostics and troubleshooting
- Compatible with standard Compact I/O power supplies and communication adapters
