Datasheet (PDF)

The 1756-OF8 is a high-performance analog output module from the Allen-Bradley ControlLogix family, engineered for precision control in complex automation systems. This 8-channel module delivers both voltage and current outputs with 16-bit resolution, enabling fine-tuned regulation of actuators, valves, and variable frequency drives. Each channel is individually isolated to protect against ground loops and electrical transients, making it ideal for harsh industrial environments. With software-configurable ranges via RSLogix 5000 or Studio 5000, the 1756-OF8 simplifies setup and reduces inventory complexity. Its hot-swappable design allows maintenance without system interruption, while compliance with global standards (CE, cULus, ATEX for safe area) ensures broad application readiness. Whether used in batch processing, continuous manufacturing, or critical infrastructure, this module provides reliable, repeatable analog output performance.
