4 20Ma Circuit Schematic

As a monolithic circuit, it offers highreliability at low cost. The current is calibrated to. In a current loop, the current signal is drawn from a dc power supply, flows through the transmitter, into the controller and then back to the power supply in a series circuit. The high pressure is connected to the pressure port and the low.
