Schneider Electric PLLA15 Pneumatic Relay

Schneider Electric PLLA15 Pneumatic Relay, manufactured by Telemecanique Pneumatics (Parker), is a pneumatic logic relay (AND element) for pneumatic signal processing in compressed-air control systems with 10-32 UNF port connections. It performs AND logic by producing an output only when both input signals are present, enabling reliable control of cylinders, actuators, and other air-operated devices in automated machinery, pneumatic sequencing systems, packaging equipment, and material handling lines. This OEM direct replacement mounts inline or on a 35 mm DIN rail, supports operating pressures from 40 to 115 PSI (3–8 bar), has a flow capacity Cv of 0.14, and operates from 0°C to +50°C. Common replacements include Parker PLLA15 and Telemecanique PLLA15.
