MTL831B HART Multiplexer

The MTL831B HART Multiplexer provides a cost-effective way to interface up to 32 HART field devices to a control system through a single RS-485 or Ethernet link. It eliminates the need for dedicated HART input cards in the DCS and provides automatic device identification and diagnostic streaming.

The 831B is widely deployed in large refineries and offshore platforms where hundreds of HART devices need to be accessed from the control room without the cost of dedicated I/O cards.
