INT-10 Signal converter for Danfoss PVG-32 proportional valves  The INT-10 is a hydraulic control component (signal converter) that converts standardized industrial control signals into the appropriate control signal for Danfoss PVG-32 proportional hydraulic valves. Danfoss valves require a control signal that is a percentage of the supply voltage. The reason for that is that the valve can be controlled by a potentiometer (joystick). The output signal of a joystick is a percentage of the supply voltage, 50% when it is in it's base position.
PLC's don't function that way. The output signal from a PLC is a standardized industrial control signal (0-10 V, -10..+10 V, 0-20 mA, 4-20 mA). The INT-10 hydrolic control component converts such a control signal into a percentage of the supply voltage. That way a Danfoss PVG-32 proportional hydraulic valve can be controlled easily by a PLC and in the appropriate way. In other words, the INT-10 solves your interface problem between PLC and Danfoss valve in a very proper and easy way.
The INT-10 has a galvanic isolation built in. That means the input and the output are electrically isolated from each other. The advantages are that interference on the power supply can't reach the PLC. And it is also allowed to reverse the input signal. A PLC with an output of 0-10 V can still drive an INT-10/5 that requires -10 .. +10 V as an input signal. So a galvanic isolation protects your precious electronics and provides ease of use.
Available models The INT-10 can be delivered in 7 different models, depending on the input signal: | Model | Input signal | | INT-10/1 | -1..+1 V | | INT-10/2 | 0-20 mA | | INT-10/3 | 0-10 V | | INT-10/4 | 4-20 mA | | INT-10/5 | -10..+10 V | | INT-10/6 | 0.5-4.5 V | | INT-10/7 | 0-8.5 V | Controlling a model /5 (-10..+10V) with a 0..+10V output signal and a relay contact The INT-10/5 is used most frequently and is most safe to use. In case the control signal is lost (broken cable, blown fuse), this unit drives the valve to it's center position. All other models will drive the valve completely open in this (error) situation. Most likely that is undesirable. So we advice to preferrably use the INT-10/5. When the only choice for the PLC's output is 0..+10V, this signal can and may be connected with reversed polarity by a relay. The relay contact switches between 0..+10V and 0..-10V (read as: controlling the A-port or the B-port). This reverse polarity switching is allowed because the INT-10 has a galvanic isolation.. Download the schematic here that shows how to switch polarity of the 0..+10V signal. This is what our customers say about the INT-10Stijn Schacht, Cenat (België) (translated from this page).
"I am very satisfied about the signal converter. It's an easy product without much cables and can be integrated in the electrical installation without much thinking. It's easy to drive it via ±10V from the PAC and to get a carefree connection to Danfoss PVG valves is really tops. Only the hydroplus controllers from Danfoss themselves provide a PVG signal directly from the PLC, so your product fills a gap in the market. The delivery time to Belgium was better than CENAT requires. Swift communication with Tildesign took care of a proper delivery.
Furthermore no problems or remarks on this product !"
