Allen-Bradley 1756-OB16IS Series A ControlLogix 16-Point Isolated Scheduled Output Module
Product Overview
The Allen-Bradley 1756-OB16IS (Series A) is a high-performance digital output module within the ControlLogix® family, specifically engineered for high-speed, deterministic control. The "IS" designation identifies this module as both Isolated and Scheduled, making it significantly more advanced than standard digital modules.
Each of the 16 sourcing channels is individually electrically isolated, providing a robust barrier against cross-channel noise and ground loops. Furthermore, the module supports scheduled output updates with an impressive synchronization accuracy of ±16.7 µs. This timing precision is critical for motion synchronization, high-speed packaging, and robotics applications where millisecond delays can lead to process failure.
