The A-B 1746-OB32 is a 32-point digital output module for the Allen-Bradley SLC 500 PLC system. It provides high-density, 24V DC sourcing outputs for controlling actuators, relays, and indicators. Featuring individual LED status indicators, robust electrical isolation, and seamless integration with SLC 500 backplanes, this module ensures reliable performance in industrial automation applications requiring precise output control.
Product Specifications
Output Type: 32-channel, 24V DC sourcing outputs (supports solenoid valves, contactors, and other DC loads).
Voltage Range: 20-30V DC per output, with 0.5A maximum current per point (non-repetitive surge up to 1A).
Isolation: 500V AC optical isolation between outputs and logic for noise immunity and safety.
Switching Speed: <1 ms turn-on/turn-off time for responsive control.
Status Indicators: Per-channel LEDs for real-time output status monitoring.
Backplane Compatibility: Direct integration with SLC 500 fixed and modular controllers (5V DC backplane powered).
Wiring: Removable terminal block for easy installation and maintenance.
Protection: Short-circuit and overload protection per channel.
Environmental Rating: Operates in 0-60°C (32-140°F) with 30g shock and 5g vibration resistance.
Certifications: UL, CE, ATEX (for hazardous locations, depending on model) compliant.
Applications: Ideal for packaging machinery, material handling, and assembly lines requiring high-density output control.
