COMMERCIAL CONTROLS Pneumatics

Receiver-Controllers • For use with remote temperature, humidity or pressure transmitters that are connected to a control variable (Cv) input • Provides restricted supply air to low volume remote transmitters, reducing air line connections between instruments to only one line • Cv input accepts transmitted output of any pneumatic device with a calibrated output of 3–15 PSIG • Direct or reverse acting — action and readjustment are field selectable • Includes hypodermic needle test points for pressure checks and output pressure gauge

• Adjustments for gain, local set point, ratio, master input balance and integral time located on controller face Specifications: • Air connection: Barb for 1/4" O.D. poly tubing • Adjustable from 0.5:1 to 15:1; factory set at approximately 10:1 • Ambient operating temperature: 50°F to 120°F • Ambient operating humidity: 10-90% R.H. at max. dew point or 85°F • 1,000 SCIM output capacity WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov

Signal Transmitter • Can be used to repeat pneumatic transmission signals, act as a high or low signal limiter, or a differential switchover device • Operates at a 1:1 ratio to compensate for pressure drops and lag times

• Provides additional capacity for a pneumatic transmitter with input to several T-5800 receiver-controllers • Proportional, direct acting • Input pressure: 25 PSI maximum WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
