A-B 1756-OF4
The A-B 1756-OF4 module is an analog output module designed by Rockwell Automation (Allen-Bradley) for its ControlLogix series PLC. It is mainly used to convert the digital signal inside the PLC into an analog signal, so as to control the external analog equipment, such as valves, motors, etc.
Main function
Analog output: The PLC’s digital signal is converted to 4-20mA or 0-10V analog signal.
High precision: provides high output accuracy to ensure the accuracy of control.
Multi-channel output: With 4 independent output channels, you can control multiple analog devices at the same time.
Flexible configuration: Supports multiple output ranges and unit configurations to meet different application requirements.
Diagnostic function: With self-diagnostic function, you can monitor the working status of the module.
