ISF-304-00 ISO4 Flow Isolator 

The ISO4 Isoflow is a signal processor that allows up to four control devices to share one flow sensor and control one master valve. 

​

The ISO4 provides four electrically isolated flow outputs and four corresponding control inputs allowing the device to selectively direct outputs only to the operating controllers. In addition it pro-vides an isolated master valve power output allowing as many as four controllers to operate one solenoid operated master valve, eliminating the need for relays. 

​

The Isoflow is compatible with all CST flow sensors and most (2 wire) sensors producing a pulse output signal proportional to flow rate. Please note: ISO4 is not compatible with Hunter HFS flow sensors. 

​

It is also compatible with all normally open or normally closed master valves with a solenoid power rating of .50 A Inrush @ 24 VAC (12 VA) or less. 

​

The ISO4 features a full array of LEDs to indicate operating conditions and aid in diagnostics. 

​

The ISO4 is expandable to eight outputs with the addition of a second module and ribbon cable.
