When using the 1769-OF8C, an external 24V DC field power supply must be connected, or the output channels will fail to function. It is essential to adhere to its distance rating of 8 slots, ensuring it is installed close to the power supply module. Additionally, shielded twisted-pair cables with proper grounding should be used to eliminate electromagnetic interference, and Safe State values must be correctly configured in the software to prevent unintended actuator movement during communication loss.
The 1769-OF8C is a Compact I/O 8-channel analog current output module designed specifically for CompactLogix control systems.
What output signal ranges does 1769-OF8C support?
It supports standard current signal outputs, typically ranging from 0...20 mA or 4...20 mA.
How to provide power to the 1769-OF8C?
It draws system power via the 1769 bus and also requires an external 24V DC field power supply to power the output loops.
What is the maximum load impedance for 1769-OF8C?
With a 24V DC supply, each channel can typically drive a load impedance of up to 500 Ω.
How is the 1769-OF8C positioned in the system?
It belongs to the Compact I/O series and can be connected directly to the right of a CompactLogix controller or via a communication adapter.
