The HART® Multiplexer Modem interfaces up to 256 smart devices (transmitters, I/P, proportional valves, etc…) in a HART® Network. Each device can be fully identified, configured and monitored either by a remote PC running an FDT-based software package (PACTware™, etc...) through a dedicated Device Type Manager (DTM), by HART® OPC Server, or by a specific asset management system. Up to 63 Multiplexer Modem (16128 loops) can be connected in multi-drop mode to the PC through the RS485 HART® Protocol, whose baudrate can be configured via software. The module is intended to be mounted on the following Term. Boards:
- TB(E)-D5001-HRT-003: to be used with GMI AI/AO Term. Boards;
- TB(E)-D5001-HRT-004: to be used with DIN-Rail mounted barriers/isolators or direct field connections, 4-20 mA loop signals,
AI card impedance = 250 Ω;
- TB(E)-D5001-HRT-005: to be used with DIN-Rail mounted barriers/isolators or direct field connections, 1-5 V loop signals;
- TB(E)-D5001-HRT-006: to be used with DIN-Rail mounted barriers/isolators or direct field connections, 4-20 mA loop signals,
AI card impedance = 100÷150 Ω;
- TB(E)-D5001-HRT-007: to be used with DIN-Rail mounted barriers/isolators or direct field connections, 4-20 mA loop signals,
AI card impedance = 0÷50 Ω.
Termination board types can be combined to manage different interfaces at the same time, provided the maximum number of channels is not exceeded.
The HART® Multiplexer Modem is SIL 3 certified as non-interfering with the signal loops.
