All Rotork Fairchild T6000, T7800 and T8000 Rack Kits utilize a 10 unit manifold.
The rack kit includes additional hardware to permit installation in a standard 19" Rack. It is suggested that transducers used with rack kits include the “ R ” option.
This option faces the electrical terminal block connector to the rear of the transducer permitting connections to the transducer to be made from the rear of the rack.
