Hart Multiplier Module, 32 Channel, 24VDC, RS-485 Interface, Up to SIL 3 acc. to IEC/EN 61508

The HART multiplexer provides 32 signal channels for connection to SMART transmitters or control devices supporting digital communication according to the HART standard. Full three-port isolation is included and each input channel has dual capacitor isolation for freedom of loop connection. Each HART multiplexer is networked simply by connecting the high-speed RS 485 output in a multidrop configuration. The device interrogates each field device, under the supervision of the workstation, retrieving information for storage in its internal database, which is then easily accessed. This module is intended to mount on an HiD Termination Board or HART Communcation Board. Also special boards for DCS integration are available.
