Johnson Controls R-3030-1 Reversing Relay 1:1 Ratio [New]

Johnson Controls R-3030-1 Reversing Relay 1:1 Ratio - The R-3030 Reversing Relay is a pneumatic auxiliary device which functions as an inverter, volume amplifier, and inverse sequencer. It is used primarily to change the output of a controller from direct to reverse acting or vice versa (see Figs. 2 and 6). With an amplified output flow, the R-3030 also achieves high speed of response and furnishes extra flow capacity to operate additional controlled devices.. Johnson Controls. Johnson Controls.
