Purchase now: Wago 750-559 Analog Output Module
Purchase now: Atlantech Drives provides you the Wago 750-559, a high-density **Analog Output Module** belonging to the Wago-I/O-SYSTEM 750. While most analog output modules offer only 2 channels, the 750-559 packs **4 Output Channels** into a standard 12mm wide housing. It generates standardized **0 to 10 V DC** control signals, making it the perfect choice for applications requiring multiple voltage control loops, such as managing lighting dimmers, HVAC damper actuators, or speed references for multiple small DC drives.
Technical Specifications and High Density
The 750-559 utilizes a common ground potential (Single-Ended) for all four channels to achieve this compactness. It offers a resolution of **12 bits**, enabling precise control steps of approximately 2.44 mV. The outputs are short-circuit proof, providing a robust interface to the field. The module derives its power for the output signal directly from the **24V DC power jumper contacts**, simplifying the power budget calculation for the bus node.

Expert Installation Advice: Load Limits
Don’t overload the voltage output. Expert Tip: The 750-559 is designed to drive high-impedance loads (> 5 kΩ). It can deliver a maximum current of roughly **10 mA** per channel. If you try to drive a low-impedance load (e.g., a 500 Ohm coil), the voltage will sag (Voltage Drop), and you won’t reach the full 10V output. Always check the input impedance of the actuator you are controlling to ensure it is compatible with a 0-10V source.
Frequently Asked Questions (FAQs)
Q: Can I use it for -10V to +10V?
A: No, this module is unipolar (0 to +10V). For bipolar signals, you need a different module (e.g., 750-556 or similar special function module).
Q: Does it require shielded cables?
A: Yes, for analog voltage signals, we always recommend shielded twisted pair cables grounded at the cabinet entry to prevent electromagnetic interference from distorting the control signal.
