SAMWONTECH ST320 PV Digital Temperature Controller (Used) in Pakistan

The SAMWONTECH ST320 PV Digital Temperature Controller from Samwontech is a high-precision controller designed for industrial temperature monitoring and process control systems. Moreover, it features a clear 4-digit display for both PV (Process Value) and SP (Set Point), allowing easy monitoring and adjustment. In addition, the controller supports universal input sensors including thermocouples, RTDs, and DC voltage signals. Therefore, it provides flexible compatibility for many industrial applications. Furthermore, with PID control, fast sampling time, and communication protocols like MODBUS and PC-Link, the controller ensures accurate, stable, and reliable temperature management in automation systems.

Features

• 4-digit PV and SP display for clear and accurate temperature monitoring.
• Fast sampling time of 250 ms for quick response and stable control.
• High indication accuracy of ±0.2% FS for precise measurement.
• Supports AUTO and MANUAL operating modes for flexible control.
• Single-loop PID control for stable and efficient temperature regulation.
• Universal input support for thermocouples, RTD sensors, and DC signals.
• Multiple alarm outputs (standard 2, up to 4 points) for safety monitoring.
• Supports MODBUS and PC-Link communication for industrial automation systems.
