The Allen-Bradley 1771-OBD is a sixteen-channel, non-isolated output module engineered for seamless integration with the PLC5 product family, making it ideal for energizing DC-powered loads such as pilot lamps, relay coils, and solenoid-actuated devices. With an output voltage range of 10-60 VDC and a nominal output voltage of 48 VDC, this module supports output channels rated at 2 A resistive, capped per module at 8 A, and accommodates pilot duty output carrying 0.2 A. Featuring impressive voltage and current specifications with a minimal load current of 2.5 mA and a maximum on-state voltage drop of 1.5 VDC, it operates efficiently with an off-state leakage current peak of 0.5 mA. Every output channel offers a surge current rating of 4 A for 10 milliseconds, repeatable every 2 seconds, and the module runs with maximum power dissipation of 15.6 W. Designed for optimal performance in a range of environmental conditions from 0 °C to 60 °C, with shock resistance and ESD immunity, the 1771-OBD is versatile and robust, ensuring reliable performance in diverse applications.
