PDES modules for the EPMS system are available with digital and analog manometer and one channel. They can be operated using an internal or an external valve. Maximum pressure is 4 bar / 58 psi.
By default the PDES modules come with an analog timer. For digital timing an additional module, TMR-02M, is required.
PDES systems are also available as 19″ stand-alone devices.
