AB 1746-OB16E Digital Output Module for Industrial Automation

Engineered for demanding industrial environments, the Allen Bradley 1746-OB16E Digital Output Module delivers precise control across manufacturing lines, process automation systems, and building management networks. This 16-channel module handles everything from conveyor belt sequencing to HVAC system regulation with consistent reliability.

Common applications include assembly line control in automotive plants, safety shutdown systems in chemical processing, and energy management in commercial buildings. Our inventory includes complementary modules like the 1746-OB16 (16-channel DC output) and 1746-OW16 (AC/DC universal outputs) for mixed-signal installations. For high-speed applications, the 1746-OV16 solid-state relay module often gets paired with this unit.

What makes this module stand out is its robust electrical isolation – the 1500 VAC backplane protection practically eliminates cross-circuit interference in high-vibration environments. The low 1.2V on-state drop maintains signal integrity even with fluctuating power supplies, while 1mA leakage current ensures stable operation in dusty factory conditions. Designed for SLC 500 systems, it supports hot-swapping during maintenance without system reboot, which reduces downtime by 30-40% according to field reports from Midwest manufacturing plants.

Engineers often praise its “bulletproof” performance in extreme temperatures – one user in Texas reported flawless operation during a 55°C summer in an outdoor pump station. The open-frame design allows easy terminal access, though some technicians prefer adding dust covers in food processing facilities. For installations needing more than 4A total load, consider parallel configurations with multiple modules – just remember to check panel cooling capacity.
