Solution: Use two IPH2 transmitters in conjunction with our SIY PCProgrammable Signal Isolator Converters to control the valves. One SIY configured for 12-4mA (reversed) and the other for 12- 20mA. At 12mA the setpoint is satisfied and both valves are closed.

Model Number Example
SIY / PRG / 4-20MA / 10-42DC [DIN]
IPH2 / 4-20MA / 3-27PSIG / 35PSI /-FR1 [WDNA]
