The 1769-OF8V is an 8-channel analog voltage output module for Allen-Bradley CompactLogix and MicroLogix 1500 systems. Each channel provides high-precision voltage outputs (0–10 V or ±10 V) for controlling devices such as VFDs, actuators, and valve positioners. Compact and 1.5-slot wide, it features per-channel configuration, integrated DACs, and short-circuit protection, making it ideal for tight enclosures and electrically noisy environments.
