Product Summary (150–200 chars)
The 1794-OC16 Flex I/O module drives 16 digital sourcing outputs at up to 60V DC and 500mA per channel. It mounts directly onto a terminal base, enabling hot-swappable field wiring without disruption.
Product Procurement & Buyer Guide
Selecting the 1794-OC16 means you gain 16 nonisolated sourcing outputs in a compact Flex I/O form factor. The module requires a compatible terminal base, such as the 1794-TB3, which provides screw-clamp connections for I/O, common, and supply lines. The keyswitch must be set to Position 2 before insertion.
This output module handles a nominal voltage of 48V DC and can operate from a minimum of 30V DC up to 60V DC at 45°C. Each channel supports an on-state current from 2.0mA to 500mA. The total output current capacity reaches 8 Amps (16 x 0.5A).
The FlexBus draws only 80mA at 5V DC, and power dissipation stays at 3.7W at 60V DC. For procurement teams, this low power consumption reduces panel cooling requirements. The module weighs just 0.11 kg and measures 94 x 94 x 69 mm, simplifying logistics and inventory storage.
Engineers appreciate the ability to swap modules without rewiring field devices. The 1794-OC16 attaches to the terminal base and locks via a keyswitch, eliminating separate terminal blocks between the controller and actuators. This design cuts installation time and material costs.
Step-by-Step User & Installation Guide
Begin by selecting a compatible terminal base unit. The 1794-OC16 works with 1794-TB3, 1794-TB3S, 1794-TB3SK, and 1794-TB3K. Ensure the terminal base is mounted on a DIN rail. Hook the base over the top rail edge, slide it against the adjacent adapter, and push down to lock.
Next, set the module’s keyswitch to Position 2. Align the module with the terminal base connector. Press firmly until the latch engages. The FlexBus connector establishes the backplane link automatically. No tools are needed for this step.
Wire field devices to the terminal base screw clamps. Use wire sizes from 0.34 mm² to 3.3 mm² (22–12 AWG). Assign output signals to terminals 0–15 on the top strip. Connect the common terminal (B-16 or B-33) and voltage supply (C-34 or C-51) for daisy-chaining.
The 1794-OC16 can be installed horizontally or vertically. The 16 yellow LEDs indicate active outputs, providing instant visual status. The module withstands 1900V DC for one second between system and user circuits, ensuring operator safety.
