Country of Origin Made in Germany. CO2 Impact By choosing this refurbished component, you are saving approximately 3.0 kg of CO2, which is comparable to the emissions from a 15 km car journey. Availability This item is in stock and ready for immediate dispatch. FAQ What is the purpose of the ‘SW’ terminal on the EMG 30-SP-10K?The ‘SW’ terminal is the wiper (or slider) of the potentiometer. As you turn the knob, the resistance between the 10V terminal and SW, and between SW and the 0V terminal, changes. This provides a variable voltage output at the SW terminal, which is used as the setpoint signal for a controller or drive. Can this module directly output a 0-20 mA current signal?No, the EMG 30-SP-10K is a passive potentiometer module. It can be used as part of a circuit to control a current signal (e.g., as an input to a PLC analog input card or a signal converter that generates the 0-20 mA), but it does not generate the current signal by itself. It simply provides a variable resistance. What is the mechanical and electrical lifespan of the potentiometer in this module?Phoenix Contact specifies a high mechanical endurance for their potentiometers, typically rated for thousands of rotational cycles. Electrically, its lifespan depends on the applied voltage and current, but as it’s designed for low-power signal applications (max 30V, max 0.5W), it offers very long operational life when used within its specified limits. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
