Product Procurement & Buyer Guide for the 1794-OV16
The 1794-OV16 is a core component for any industrial control system. This module delivers 16 isolated sinking outputs for precise DC load control. You can use it to drive solenoids, indicators, and relay coils. The module operates with a nominal 24V DC on-state voltage. It supports an operating range from 10 to 31.2V DC. This flexibility allows integration into various existing systems. Each channel can handle a maximum current of 500mA. The total module output current is rated at 8.0 Amps.
This output module features a fast switching performance for critical tasks. The off-to-on delay time is only 0.5 milliseconds. The on-to-off delay time is a maximum of 1.0 milliseconds. This speed ensures tight control over actuator responses. The module also has a low on-state voltage drop. The maximum drop is just 0.2V DC per channel. This reduces power loss and heat generation. The power dissipation is only 4.2 Watts at 31.2V DC.
For installation, you must use a compatible terminal base unit. The 1794-OV16 fits with the 1794-TB3 or the 1794-TB3S. These bases provide the wiring connections to field devices. You then snap the module onto a standard DIN rail. This open-style module has an IP20 protection rating. This rating is suitable for use inside a clean control cabinet. The module supports popular network protocols including ControlNet and EtherNet/IP.
When you order this unit, verify the external power supply requirements. The module needs a 10 to 31.2V DC supply with 20 to 65 mA current. The supply can have up to 5% AC ripple. The module draws 80mA from the FlexBus. It also features 16 yellow LED indicators for quick status checks. These LEDs show the state of each output channel. This makes troubleshooting a disconnected wire very simple.
Step-by-Step Installation Guide for Flex I/O
Begin your installation by mounting the terminal base unit on the DIN rail. For the 1794-TB3, hook the base over the top rail edge. Push the base downward until it locks into place. Ensure the FlexBus connector aligns with the adjacent adapter. Tighten the base against the unit to secure the connection.
Now you can wire your field devices to the terminal base. The top strip holds 16 terminals for I/O connections. The middle strip contains 18 common terminals and the bottom strip holds 18 supply terminals. Use a wire size between 0.34 and 3.3 mm². The screw clamp terminals require a torque between 0.56 and 0.79 Nm.
After wiring, you can install the 1794-OV16 module onto the base. Simply slide the module into the slot until it snaps securely. You can insert or remove this module while the system is live. This hot-swapping capability saves significant maintenance time. It also eliminates the need for a full system restart.
Finally, apply power to the system and check the channel status. The yellow LEDs will illuminate when the output channel is on. Confirm that the load activates as expected. The module operates in temperatures from 0 to 55°C. It can handle noncondensing humidity from 5 to 95%. For extreme environments, an XT version is available.
