MTL4015 Dual Relay Interface – Safe & Hazardous Area Signal Conversion
Product Description
The MTL4015 is a robust interface module designed to connect hazardous area sensors (Zone 0/Div.1) to two safe-area control systems. Featuring dual relay outputs, it’s perfect for critical applications like process control and emergency shutdown systems. With line fault detection and phase-reversal capability, this module ensures reliable operation in oil & gas, chemical, and industrial plants.
