Product Description

The SM302J-PA20 module integrates the SM-302J sensor with the PA20 pressure transmitter, offering dual analog inputs for pressure measurement and one configurable 4-20mA output. Designed for industrial automation, this compact unit directly interfaces with PLCs and SCADA systems via RS-485 Modbus RTU, supporting up to three peripheral modules in daisy-chain configurations. Operating within 12-30V DC power and -40°C to +85°C temperature ranges, it excels in harsh environments like oil/gas pipelines and wastewater treatment plants. Equipped with a 3.2" LCD, the IP67-rated device delivers ±0.25% F.S. accuracy across its 0-20MPa measurement span, featuring 5000mAh backup power for critical applications. While optimized for vibration resistance and EMI immunity, installation requires professional calibration.
