Specification

SEODescription

The SUZst-PSA16, part of the SUZst Pressure Switch series, is a compact industrial-grade PSA16 Pressure Switch designed for precise pressure monitoring. It features 1 analog input for pressure sensing and 2 configurable digital outputs (relay/PNP), supporting direct connection to up to 4 sensor modules via its integrated RS-485 interface with Modbus RTU protocol. Operating within 12-30V DC, it withstands temperatures from -40°C to +85°C, making it ideal for harsh environments in oil/gas, water treatment, and HVAC systems. Its IP67-rated housing ensures dust/water resistance, while a 0.5% FS accuracy enables reliable control. Though highly durable, the PSA16 Pressure Switch requires periodic calibration and may need signal conditioning for low-pressure applications below 0.5 bar.
