Engineered for high performance, the Allen Bradley 1793-OB16P is a component of the FLEX I/O 1793 series and serves as an output module. It features an impressive configuration with 16 channels dedicated to sourcing protected outputs. This means it is able to supply conditions where the output voltage can range from a minimum of 10 V dc up to a nominal value of 24 V dc, and reaching a maximum of 31.2 V dc.

In terms of channel performance, this module provides on-state currents ranging from a minimum of 1 mA to a maximum of 500 mA, making it suitable for diverse operational needs. The off-state leakage current does not exceed 0.5 mA, ensuring minimal wasted energy. It can handle surge currents of 1.5 A for a duration of 50 milliseconds, with the ability to repeat this every 2 seconds, demonstrating resilience under transient conditions. The delay times are efficient, with 0.5 ms max from off to on, and 1.0 ms from on to off, providing quick response times.

The module has a maximum Flexbus current draw of 80 mA, while it maintains power dissipation at 5.0 W when operating at the maximum output voltage of 31.2 V dc. The thermal dissipation is rated at 17 BTU/hr under the same voltage conditions. For real-time monitoring, each channel has a dedicated yellow status LED indicator, totaling 16 LEDs, enabling an operator to easily observe operational status. Additionally, the design allows for DIN-rail mounting, optimizing installation flexibility. Compliance certifications include UL, CE, and Class I Div 2 Groups A-D, ensuring reliable operation in a variety of settings.
