I am in need of a solution for connecting a 4-20mA proportional signal to a valve with only floating control inputs. While the valve does have a 4-20mA feedback option, I am looking for a premanufactured device that can facilitate this connection seamlessly. Is there a convenient and simple solution available for this type of setup?

Thank you for the information. The valve I have has a fast response time of 4 seconds to go from fully closed to fully open, which is much quicker than the 30-second minimum of the options you provided. I have been looking for signal conditioners tailored to floating point control, but my search yielded limited results. Most of the available options seem to focus on converting between voltage, current, and PWM signals.
Optimize performance with adjustable deadband for each relay by ACI AAR transducers and multiplexers available on kele.com. Improve control accuracy and efficiency with customizable deadband settings for every relay.
For a PLC application, all that's needed is to craft a few logic rungs.
According to TWS, an adjustable deadband for each relay should be effective. Visit kele.com for ACI AAR transducers and multiplexers. This solution seems perfect and is currently available for only $20 on eBay, making it a budget-friendly option. Unfortunately, I lack control over the original signal, so installing a PLC solely for this purpose is not a viable solution.
You might want to consider using a signal converter/conditioner that can convert the 4-20mA signal to the necessary input for your valve. Companies like Omega Engineering or Phoenix Contact manufacture such devices. These can seamlessly facilitate the connection you're seeking without needing any complex changes to your current system. But just make sure the converter specifications align with your system's requirements before making any purchase.
You might want to consider using a 4-20mA signal conditioner or a loop-powered isolator that can interface between your signal source and the valve. Devices like the Siemens SITRANS LUT400 or the Red Lion PAX2C can effectively convert and isolate signals for better compatibility with floating control inputs. These solutions are designed for seamless integration and can simplify your setup significantly, ensuring that you maintain accuracy without needing extensive customization. Just double-check the specifications to ensure the device meets your specific requirements!
You might want to look into using a 4-20mA signal isolator or a signal converter; these devices can help translate your current signal to something compatible with the valve's floating control inputs. Some manufacturers, like Analog Devices or Moore Industries, offer ready-made solutions that are designed specifically for this purpose and can streamline your setup without needing extensive custom wiring. Just make sure to check the specifications to ensure compatibility with your system!
