Safety temperature limiter STL50EX

Intrinsically Safe Safety Temperature Limiter for Hazardous Areas

The STL50EX Safety Temperature Limiter is an intrinsically safe safety controller designed for monitoring thermal processes in hazardous (Ex) areas. It immediately switches connected systems to a safe operating state whenever temperature limits are exceeded or a system fault occurs. Certified to DIN EN 14597, EN 61508 (SIL2), and EN ISO 13849 (PL d), it ensures dependable protection for safety-critical industrial applications.

Key Features:

  • 🛡️ Intrinsically Safe Ex Inputs

    Designed for ATEX hazardous areas, the STL50EX safely connects to approved temperature sensors installed in explosive environments for reliable thermal protection.

  • 🌡️ Certified Safety Protection

    Certified to DIN EN 14597, SIL2, and PL d standards, providing dependable over-temperature monitoring for industrial safety applications.

Key Features:

  • 🚨 Intelligent Alarm & Fast Shutdown

    Instantly detects over-temperature, sensor break, short circuit, power supply faults, and internal errors, activating safety relays and external alarms without delay.

  • 📟 LCD Display with Easy Configuration

    Features a graphic LCD display with plain-text diagnostics, front-panel programming, password protection, and optional analog output for simple operation and system integration.
