Allen-Bradley 1756-0B16E 16-Point DC Output Module

The Allen-Bradley 1756-OB16E (often cataloged as 1756-0B16E) is a ControlLogix 16-point DC output module with electronically fused 24 VDC outputs, designed to reside in a ControlLogix I/O backplane for reliable, field-driven control of loads. Each of the 16 outputs is independently capable of switching up to 1 A at temperatures up to 60°C, delivering up to an 8 A total module current across all points and a maximum heat dissipation around 4.1 W. The module accepts a DC supply in the 10–30 V range (12–24 V is typical for common DC loads) and uses removable 20‑pin terminal blocks (1756-TBNH or 1756-TBSH) for easy field wiring in a standard ControlLogix chassis. It draws backplane current of roughly 250 mA at 5 V and provides continuous isolation of 50 V between the outputs and the backplane, making it suitable for switching DC coils, relays, and other DC actuators in industrial automation applications while preserving system safety and reliability.
