CST Isoflow ISO4
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 provides 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.
