ICP-DAS releases a new version of HART to Modbus RTU / TCP protocol converters that can operate at extremely low temperatures down to -40 °С. New models get the -UTA prefix.
HRT-310 and HRT-710 gateways serve one and the same function - they convert HART Master to Modbus RTU/ASCII Slave and backwards, however HRT-310 model is more recent and features better characteristics.
|HART signal||Standard||Extended communication distance|
|Support of loop power||No||Support (module provides +30V output)|
|Built-in resistor||250 Ohm (1/4 W)||250 Ohm(1 W)|
HRT-711 gateway converts HART Master to Modbus TCP Slave.
|HRT-310-UTA||Modbus RTU/ASCII Slave to HART Master gateway, 1xRS-232/422/485, slim housing, -40...+75°C|
|HRT-710-UTA||Modbus RTU/ASCII Slave to HART Master gateway, 1xRS-232/422/485, -40...+75°C|
|HRT-711-UTA||Modbus TCP Server to HART Master gateway, 1xLAN, -40...+75°C|
