Temperature limiter TB225

Universal Temperature Limiter & Monitor for Safe Thermal Process Control

The TB225 Temperature Limiter is a versatile safety device designed to monitor thermal processes and safely shut down equipment when preset temperature limits are exceeded or a system fault occurs. It functions as both a temperature limiter and temperature monitor, offering universal signal inputs, configurable relay outputs, and optional SIL2 certification for safety-critical industrial applications.

Key Features:

  • 🌡️ Temperature Limiter & Monitor

    Operates as both a temperature limiter with manual reset and a temperature monitor with automatic reset, providing flexible protection for a wide range of thermal processes.

  • ⚙️ Universal Signal Compatibility

    Supports Pt100 sensors, thermocouples (J, K, N & S), and standard analog signals (0/4–20 mA, 0/2–10 V) for maximum application flexibility.

Key Features:

  • 🚨 Dual Relay Outputs & Analog Output

    Features two programmable relay outputs for safety shutdown and pre-alarm indication, along with an isolated analog output for integration with PLC and SCADA systems.

  • 📟 Intuitive Graphic LCD Display

    Equipped with an illuminated graphic LCD display that changes from white to red during alarm conditions, making process status easy to identify at a glance.

Applications:

  • 🔥 Industrial Heating Systems

    Protects boilers, furnaces, ovens, kilns, and other heat-generating equipment against unsafe temperatures.

  • 🏭 Thermal Process Monitoring

    Provides reliable temperature supervision for manufacturing, processing, and industrial automation systems.

  • ⚙️ Machine & Equipment Protection

    Safeguards critical machinery by automatically initiating shutdown when temperature limits are exceeded.

  • 🤖 PLC & Process Automation

    Integrates easily with PLCs, SCADA systems, and industrial control panels through relay and analog outputs.
