Universal interface

A system comprising:

• one or more sensors configured to detect one or more operating parameters of an industrial system;
• an interface circuit configured to couple to the one or more sensors and receive one or more sensor signals, wherein a first sensor signal of the one or more sensor signals is indicative of a first operating parameters of the one or more operating parameters, wherein the interface circuit includes:
• an input circuit comprising:
• a first input pin, a second input pin and a third input pin,
• a first operational amplifier comprising:
• a first output pin,
• a first non-inverting input pin electrically coupled to the first input pin via a first impedance and a first switch,
• a first inverting input pin coupled to the first output pin;
• a second operational amplifier comprising:
• a second output pin,
• a second non-inverting input electrically coupled to the second input pin via a second impedance,
