The Allen-Bradley 1769-OB32 is a high-density 32-point sourcing output module engineered for demanding CompactLogix control architectures. Designed for 24V DC control applications, this module delivers 0.5A per output (8A total per module at 60°C) with robust short-circuit protection and individual diagnostic LEDs. Its compact form factor and removable terminal block (RTB) simplify field wiring and maintenance, while supporting hot-swap replacement under power. Ideal for automotive, packaging, and material handling systems, the 1769-OB32 ensures reliable high-speed switching with minimal heat dissipation.
