I have a vacuum gauge with on board relays that trip at set pressures. They have a rating of 30 VDC, 1 A. The solenoid valve I need to control is 50 VDC with max current 3A (also is inductive load of course).
What is my easiest, cheapest option here to still use the vacuum gauge relay to control the solenoid? It seems like I need the relay to complete the circuit of an amplifier input that can provide the current and power drawn by the solenoid. I just need to figure this out fast, any help in the right direction in terms of products is appreciated.
