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. Key Features: Outputs: 16 individually isolated DC sourcing outputs. Voltage Range: Operates at 10–30 VDC. Output Current: Up to 2 A per point at 30 °C, 1 A at 60 °C. Module Current: 8 A maximum at 30 °C, 4 A at 60 °C. Switching Speed: 1 ms ON delay, 2 ms OFF delay. Surge Protection: 4 A for 10 ms, repeatable every 2 seconds. Isolation: Channel-to-channel and user-to-system isolation tested to 250 V AC continuous. Diagnostics: LED indicators for module and point status. Wiring: Requires 36-position RTB (1756-TBCH or 1756-TBS6H). Certifications: UL, CSA, CE, ATEX for industrial and hazardous environments. The 1756-OB16I delivers the flexibility, isolation, and reliability required for demanding industrial digital output applications.
