摘要:
An electronic regulator includes an inlet valve coupled to an inlet port, the inlet port configured to receive a supply pressure, and an exhaust valve coupled to an exhaust port, the exhaust port configured to release a pilot pressure when the exhaust valve is open. The electronic regulator also includes a pilot pressure output pneumatically coupled to the inlet valve and exhaust valve and configured to be coupled to an external process control device to provide the pilot pressure to the external process control device. A setpoint input coupled to both the inlet valve and the exhaust valve receives a setpoint signal indicative of a setpoint value, and the electronic regulator operates the inlet valve and the exhaust valve to control the pilot pressure according to the setpoint value. Further, the electronic regulator includes a vent valve coupled to a venting port and pneumatically coupled to the pilot pressure output. The venting port is configured to release the pilot pressure according to the safety control signal.
