Description:

• Genuine Allen-Bradley SLC 500 digital DC output module for industrial PLC and automation applications
• Provides 16 sourcing digital output channels for controlling 24 VDC field devices
• Operates with an output voltage range of 10–50 VDC, suitable for general-purpose DC load switching
• Supports continuous output currents of up to 0.5 A per point (30°C) and 8 A per module (30°C)
• Designed for controlling relays, solenoids, pilot lights, contactors, valves, and other DC output devices
• Front-panel LED status indicators provide clear output diagnostics and troubleshooting
• Installs in any SLC 500 (1746) chassis slot except Slot 0
• Screw-clamp removable terminal block simplifies installation and maintenance
• Ideal for machine automation, process control, packaging equipment, material handling, OEM machinery, and industrial control systems
• Discontinued by Rockwell Automation, making it ideal for replacement and maintenance of legacy SLC 500 installations.
