Eaton MTL5521 Intrinsically Safe Solenoid and Alarm Driver Hazardous Area DIN Rail Module

The Eaton MTL5521 is a loop-powered solenoid and alarm driver designed for controlling intrinsically safe devices in hazardous areas from a safe area interface. Part of the MTL5500 intrinsically safe isolator range, this module enables reliable switching of certified low-power loads such as solenoids, alarm circuits or simple apparatus like LEDs in explosive atmospheres. The loop-powered design simplifies wiring and reduces installation complexity in industrial process control systems.

The MTL5521 is suitable for Zone 0, IIC gas group hazardous locations when used within its certification limits, and offers robust performance across a wide supply voltage and temperature range. A yellow LED indicator shows output status for easy diagnostics.
