The Allen-Bradley 1756-OB16D ControlLogix® Sourcing Output Module delivers robust control for industrial actuation systems. Designed for Rockwell's ControlLogix platform, this 16-channel module sources 24V DC power to solenoids, relays, and starters with galvanic isolation (1,500V AC) between outputs and backplane.
Featuring a hardened aluminum housing (-40°C to +70°C) with NEMA 4X/IP67 protection, it withstands washdowns, corrosive chemicals, and vibration (5g IEC 60068-2-6). Integrated per-channel diagnostic LEDs, electronic keying, and 0.5A continuous per-point capacity ensure precise control in demanding automation environments. Studio 5000® enables configurable pulse stretching (1-65,535ms) and real-time health monitoring.
