SMC 10-PSE300-LAC | Clean Room 2-Color Digital Pressure Sensor Controller PSE300 Series Remote Type Display Unit

The SMC 10-PSE300-LAC is a clean room specification 2-color digital pressure sensor controller from the PSE300 series, serving as a remote display and control unit. Part number decoded: PSE300 = remote-type pressure sensor controller, LAC = specific configuration code for display, output, and communication options. The PSE300 is not a pressure sensor itself — it is the controller/display unit that pairs with remote PSE pressure sensor heads to provide centralized monitoring and switch output control.

Why use a remote controller instead of an integrated pressure switch? In clean room equipment, the pressure sensing point is often deep inside the machine where display visibility is impossible. The PSE300 controller mounts in an accessible location (control panel face, operator interface) while the compact remote sensor head mounts at the measurement point. This separation allows pressure monitoring without opening equipment enclosures, reducing particle introduction from maintenance access. The 2-color LED display (red/green) provides instant visual status: green for normal, red for alarm conditions.

The PSE300-LAC provides programmable switch outputs for PLC integration, allowing high/low pressure alarm thresholds and hysteresis to be configured from the display unit. For the remote sensor heads that pair with this controller, the PSE540 (pneumatic) and PSE560 (general fluids) series provide the measurement points. Multiple sensor heads can connect to a single PSE300 controller for multi-point monitoring. Compatible with SMC clean series pneumatic equipment. Clean series (10-) Particle Grade 1. RoHS compliant.
