The 1794-OE12 ALLEN-BRADLEY FLEX I/O Analog Output Module is a versatile and rugged 12-channel output interface designed for distributed control systems in process and discrete manufacturing. As part of the FLEX I/O family, this module provides seamless integration with Rockwell Automation controllers via the FlexBus backplane. The 1794-OE12 delivers 16-bit resolution on each channel, supporting both voltage (0-10V, ±10V) and current (0-20mA, 4-20mA) outputs with individual channel configuration. Its channel-to-channel isolation (1500V DC) ensures reliable performance in electrically noisy environments, making it ideal for valve positioning, actuator control, and signal conditioning applications. The module is housed in a compact, DIN-rail-mountable package with a NEMA Type 1 or IP20 rating, ensuring durability in factory floor conditions. Each output channel features overcurrent and short-circuit protection, and the module includes a user-configurable fault mode for safe state operation during communication loss. The 1794-OE12 is CE, UL, and CSA certified, meeting global industrial standards.
