Description
1746-NIO4V A-B 2-channel voltage output analog combination module
Product Dimensions：
Product Description (Detailed Explanation)
The 1746-NIO4V features 2 Analog Input channels and 2 Analog Output channels. This module is ideal for smaller systems where rack space is limited but both sensing and control capabilities are required.
-
Inputs: The two input channels are universal and can be configured for various voltage or current ranges (though typically used for voltage in this “V” designated model).
-
Outputs: The two output channels are specifically designed for Voltage Output (e.g., 0 to 10V DC). This makes it perfect for controlling actuators that require a voltage reference, such as variable frequency drives (VFDs) or proportional valves.

Product Advantages (Key Benefits)
-
Space Efficiency: By combining inputs and outputs into a single slot, it reduces the overall chassis size and system cost.
-
High Resolution: With 14-bit resolution, it provides precise control and sensing for sensitive industrial processes.
-
Differential Inputs: The inputs are differential, which helps reject common-mode noise, ensuring signal integrity in electrically “noisy” factory environments.
-
Simplified Spares: Maintenance teams only need to stock one module type to cover both input and output functions for a specific loop.
Precautions (Important Notes)
-
Output Loading: Ensure the load impedance on the voltage outputs is at least 1000 ohms. Loading the output too heavily can result in inaccurate voltage levels or module damage.
-
External Power: This module draws significant current from the 24V DC backplane bus. Verify that your SLC 500 power supply (e.g., 1746-P1 or P2) has enough remaining capacity.
-
Shielding: Use twisted-pair, shielded cable for all analog signals. The shield should be grounded at only one end (usually at the PLC rack) to prevent ground loops.
-
DIP Switch Configuration: The input types must be configured via internal DIP switches before the module is inserted into the rack.
Product Applications (Typical Use Cases)
-
VFD Speed Control: Sending a 0-10V signal to a motor drive while receiving a 0-10V speed feedback signal.
-
Temperature/Pressure Loops: Measuring a process variable via an analog transmitter and outputting a control signal to a motorized damper or valve.
-
Tension Control: Monitoring web tension in paper or film processing and providing a corrective voltage signal to a brake or clutch controller.
-
Level Management: Using ultrasonic level sensors (input) to trigger and modulate a variable-speed pump (output).
