MTL838B | MTL | Analogue Multiplexer Receiver

Description:

The MTL838B Receiver is designed to support hazardous-area applications by reducing the cost and complexity of installing hazardous-area cabling. It provides reliable status reporting, sensor failure detection, and integrates directly with host systems via serial-data outputs. This device is equipped with dual RS485 Modbus® outputs and is suitable for a range of industrial process control environments.

Key Features:

• Dual Redundant Data Highways: Two data highways that are dual redundant; either or both may be used.
• Status Reporting: Quickly highlights problems through its status reporting systems.
• Sensor Failure Detection: Includes safety drives to protect the process by detecting sensor failures.
• Serial Data Outputs: Connects directly to host systems through dual RS485 Modbus® outputs.
• Reduced Cabling Costs: Designed to reduce installation time, space, and weight in hazardous areas.
