The ICO4-SIS is the first fully integrated partial stroke testing solution with the control system built into the market leading IMI Maxseal ICO4 high integrity solenoid valve. With the lowest safe and dangerous failure rates of any intelligent PST system on the market and always providing the highest possible Diagnostic Coverage, the best possible SIL performance is guaranteed.

> No dedicated PST device required therefore signi cantly reduces engineering requirements

> High level diagnostics with position, pressure and time monitoring

> Simple Pass/Fail reporting
> Dual override mechanism eliminates possibility of over-stroke > Compatible with valve speeds from 2 to 120 seconds
> SIL 3 certi ed as 1oo1
> -40°C ... +70°C

> Local testing using HART 475 communicator, remote testing via HART
