R539 (2378-501) TAC PNEUMODULAR � 2:1 Ratio Amplifying Relay The amplifying relay is a proportioning device designed for use in pneumatic control systems where the application requires the amplification of a proportional signal from a controlling device. The relay’s branch line pressure output increases as a 2:1 ratio to the input signal pressure (up to main air pressure) and amplifies the volume of air available to the final control device, thereby minimizing system lag. Features: • 2:1 signal amplifying relay, with adjustable bias. Output changes are equal to input changes multiplied by two. • Ideal for applications such as: - Operating two actuators, that have the same spring range, in sequence (using two R539s and their bias adjustments). - Narrowing the throttling range of any pneumatic controller (or portion of an operating sequence) by a factor of two. - Factory set for 10 psig branch pressure at 5 psig input pressure at port S1. • All ports clearly labeled. Ports align with MCS-S terminals. • TAC PNEUMODULAR: Mounts on MCS-Socket or K502 Mounting Bracket. Model Chart Model No. Specifications Wholesale Model No. R539 2378-501 a a Includes plastic mounting strap and adhesive backed mounting plate. Port Connections Port Connected to M Main air B Branch output S1 Input signal Action Proportional output at 2:1 ratio. Construction Glass-filled nylon. Maximum ambient temperature 140�F (60�C). Supply air pressure Clean, dry, oil free air required (Ref. EN-123). Nominal 20 psig (138 kPa). Maximum 30 psig (207 kPa). Connections Barbed fittings for 1/4 in. O.D. polyethylene or 5/32 in.
