Information About 1756-OB16I
The 1756-OB16I is part of the Allen-Bradley ControlLogix family, developed to deliver flexible, high-performance output control. It supports 16 isolated outputs, each rated for up to 2 A at 30 °C or 1 A at 60 °C, with a maximum module current of 8 A at 30 °C and 4 A at 60 °C. Outputs are configurable for fault and program modes, with options including hold last state, ON, or OFF. The module operates with fast response times, featuring 1 ms OFF-to-ON and 2 ms ON-to-OFF switching. It requires a 1756 chassis and compatible RTBs such as the 1756-TBCH or 1756-TBS6H for wiring. The 1756-OB16I provides diagnostic LEDs for status indication, supports direct-connect or rack-optimized communication formats, and synchronizes scheduled outputs with the ControlLogix system clock. It also offers surge protection of up to 4 A for 10 ms per point, repeatable every 2 seconds. With industrial certifications including UL, CSA, CE, and ATEX, the module is suitable for standard and hazardous location applications.
