2 eries 40 Pneumatic Indicating Controllers Pneumatic indicating controllers are used for the automation of process and industrial plants. he controllers measure the controlled variable directl pressure, temperature, electric or pneumatic standardized signal compare the measured value ith the set point and deliver a pneumatic control signal of 0. to bar ( to 5 psi). A suppl pressure of.4 bar (0 psi) or an operating pressure of to bar (0 to 80 psi) is required. he modular controllers represent a complete automation package consisting of a controller station, a controller module suitable for the respective task, and, if necessar, a transmitter module as ell as other additional equipment. hus, onl one indicating controller and one control valve are needed to set up a pressure or a temperature control loop. Can be equipped ith transmitter modules for pressure or temperature (capillar tube sensor or Pt 00 resistance thermometer). tandardized controller ith input of 0. to bar, to 5 psi, 4 to 0 ma, 0 to 0 ma or to 5 ma. uitable for fied set point, follo-up or cascade control. et point, actual value, deviation, and signal pressure are visible at a glance. All adjusters and sitches can be operated from the front. Can be equipped ith controller modules for P, PI, PID or PD control and supplementar modules for special control tasks. Housing for all mounting, tube mounting, and panel mounting (front frame 9 44 mm or 9 8 mm) All pressures are stated in bar (gauge) unless specified otherise. able Instrumentation ith pneumatic indicating controllers Pressure control emperature control tandardized signal control Pneumatic Pneumatic Electropneumatic Pneumatic Electropneumatic A Fied set point control p H/A i/p H/A 5 i/p Capillar tube sensor 7 8 p p,, p p,, p, Q Pt 00 B Follo-up control p et et et H/A i/p et H/A 4 i/p 5 i/p et Capillar tube sensor 7 8 p p,, p p,, p, Q Pt 00 C Cascade control pe 4 Controller tation ith transmitter module pe 4 or pe 4 Controller tationithout transmitter module ransmitter module for pressure or temperature 4 i/p converter for eternal reference variable et 5 i/p converter or converter module for controlled var.
