The Allen-Bradley 1756-OB16D is a high-performance ControlLogix DC diagnostic output module equipped with 16 electronically fused outputs, divided into two groups of eight per module. This module offers robust diagnostic capabilities, including no-load and output verification detection, configurable output states in both Fault and Program modes, and diagnostic latching. It operates within a voltage range of 19.2 to 30V DC, supports a linear derating output current up to 2 A at 30 °C, and demands a backplane current of 140 mA at 24V DC; the module can be effortlessly integrated into any compatible ControlLogix chassis with the requisite 36-position removable terminal block housing, either 1756-TBCH or 1756-TBS6H, facilitating seamless installation and operation. With an operational temperature tolerance from 0 to 60 °C and a swift output delay time, the 1756-OB16D is engineered for precision and reliability in demanding industrial environments.
