The 1799-D16U16VL is an output digital embedded I/O module crafted by Allen Bradley within the 1799 Embedded I/O series. Operating effectively at 24 VDC, this module is engineered to accommodate a variety of I/O connection methods such as cyclic, polled, and change-of-state. It supports a total of 16 inputs and 16 outputs per block, operating in either sinking or sourcing configurations, ensuring adaptability for multiple system designs.

Each input and output has well-defined operational parameters. The off-state voltage is capped at 5 VDC, while the maximum off-state current is 1.5 mA, ensuring minimal power usage when the device is not active. Upon activation, the module allows an on-state current ranging between 2 to 6 mA, reflecting efficient performance characteristics. The on-state voltage drop is restricted to a maximum level of 250 mV, indicating low resistance during operation. Furthermore, the off-state leakage current is limited to 65 μA, underscoring the reliability of the module under idle conditions.

The device also incorporates a Class 2 power circuit type for DeviceNet applications, which assures compliance with industry standards. Auxiliary power current outputs can provide up to 30 mA when powered off. The overall power dissipation is managed, with a maximum rating of 5 watts, making the 1799-D16U16VL a suitable choice for embedded control systems that require digital input and output capabilities.
