8 to 56 channel HART fieldbus gateway device that interfaces a network of HART compatible devices to a Modbus Host computer. System configuration features provide setup for many different control schemes and system requirements.
Intelligent serial multiplexer designed to convert between the HART and Modbus protocols. Up to 64 HART channels may be driven from a single device, added in multiples of 8 channels at a time. Both point-to-point and multidrop mode is supported, subject to a maximum of 512 transmitters per HtMux. Data is handed off via two RS232 serial ports using the MODBUS RTU protocol.
The HtMux is supplied as a 3U high cardframe suitable for mounting in a 19? rack, with all signal and power connections being made to the front. RS232 Modbus connections are available via two 9 pin ?D? type connectors. Build options are available for 110/220 Vac and 24Vdc. A further option exists for data to be handed off using the Modbus protocol wrapped in TCP/IP frames on Ethernet.
