The 1794-OC16 Flex I/O module delivers robust digital output control for demanding industrial systems. This module provides 16 nonisolated sourcing outputs for reliable actuator and indicator management. It integrates seamlessly into the Allen-Bradley Flex I/O platform.
Product Procurement & Buyer Guide
You need a module that offers high-density output control in a compact footprint. The 1794-OC16 solves this need with 16 channels in a single unit. Each channel delivers a sourcing output for direct control of DC loads.
This module operates at a nominal 48 Volts DC. Its output voltage range spans from 30 Volts DC up to 60 Volts DC. This flexibility suits various industrial solenoid and relay applications. The maximum on-state current per channel reaches 500mA.
The total output current rating for the module is 8 Amps. This calculation uses 16 channels multiplied by 0.5 Amps each. This module manages loads like indicator lights and motor contactors. It eliminates the need for separate terminal blocks between logic and field devices.
The module requires a compatible Flex I/O terminal base unit. Compatible bases include the 1794-TB3, 1794-TB3S, and 1794-TB3SK. The keyswitch on the terminal base must be set to Position 2. This ensures correct mechanical and electrical alignment.
The module draws 80mA from the FlexBus at 5 Volts DC. Its power dissipation is 3.7 Watts at 60 Volts DC. These specs help you calculate the total system power budget accurately. This module helps panel manufacturers reduce wiring complexity.
Expert Technical Evaluation & Performance Review
The 1794-OC16 module features 16 yellow LED indicators. These LEDs clearly show the on/off status for each output channel. This provides immediate visual feedback for troubleshooting and commissioning.
The digital outputs are nonisolated from each other. This design keeps the module compact and cost-effective. However, the module withstands 1900 Volts DC for one second between the system and users. This high-voltage test ensures operator safety.
The off-state voltage maximum is 60 Volts DC. The off-state leakage current remains below 1.0mA. This low leakage prevents false triggering of sensitive loads. The on-state voltage drop is a maximum of 1.0 Volts DC at 0.5 Amps. This minimizes power loss and heat generation.
The module requires a minimum on-state current of 2.0mA per channel. This ensures reliable switching for low-current loads. The module weighs just 0.11 kilograms for easy handling. Its dimensions are 3.7 by 3.7 by 2.7 inches.
You can install this device either horizontally or vertically. This mounting flexibility simplifies panel layout design. The module attaches directly to the terminal base without tools. This allows for quick swapping without disturbing field wiring.
