Hi Anurag,

The Jetronic-Box by EVOJET (used to be called ORBIT), is by far the best "Electro/Pneumatic" unit on the market today. I use them in ALL my jets with the PRO-HV Dual Action Valves and PRO-HV Brake Valve.

Plus it has a "Failsafe" feature for all the pneumatic's. You will however need the EDT for set-up. If you use the small EDT unit it can also be permanently mounted on-board - if you wish.
