C-9506-1 Johnson Controls Cumulator

The Johnson Controls C-9506-1 Air Switching Cumulator; Cumulator Air Switching

Datasheet

The C-9506 Air Switching Cumulator is an auxiliary device designed to switch its output pressure from zero to full supply pressure when the pilot pressure reaches the switch point. It is ideally suited for exhaust damper applications requiring a high output volume for quick operation. The switch point is factory set at approximately 9 PSIG (63 kPa) and is adjustable from 2 to 12 PSIG (14 to 84 kPa). The C-9506 also doubles as the unit replacement for all models of D-9502 and V-9502 Positioners.

Operation

The C-9506 is a two-position device with a 1 PSI (7 kPa) differential. When the pilot pressure is below the switch point, the output will be zero. As the pilot pressure rises above the switch point, the output will switch to full supply pressure. When the pilot pressure drops to 1 PSI below the switch point, the output pressure will drop back to zero.
