Floating Point to Pneumatic
The SC-PTS4.1 converts two digital (increase/decrease)signals (relay contact closure, transistor or TRIAC) into a proportional pneumatic signal. The SC-PTS4.1’s closed loop electronic design will maintain the last commanded pneumatic pressure. An on-board microprocessor measures the signal input, and a solid-state pressure transducer measures branch line pressure. The SC-PTS4.1 uses these two values to automatically increase or decrease branch line air pressure.
