The MTL831C is an analog transmitter designed to transfer multiple hazardous area input signals to a safe area using a single shielded, twisted-pair cable. This setup, often called a data highway, ensures simplicity in installation.

Key Features and Capabilities

• Multiple Input Channels: Monitors up to 16 inputs from sources like thermocouples, millivolt sources, or 2, 3, or 4-wire RTDs/potentiometers.
• Hazardous Area Compatibility: Intrinsically safe for installations in Zone 0 hazardous areas.
• Data Highway: Simplifies installation by transmitting data over a single cable.
• Configuration Flexibility: Allows configuration for various input types and measurement parameters.
• Burnout Detection: Monitors thermocouple resistances to detect potential burnouts.
• Cold Junction Compensation: Automatically compensates for temperature variations at the measurement point.
