The UNICOMM interface modules are able to establish communication line between HART-capable field devices and process controller computer. The communication line can be USB or RS485. The UNICOMM HART modems are applicable not only for NIVELCO transmitters, but for all HART-capable transmitters which use standard HART communication. The device is galvanically isolated from both (USB and HART) sides, when it is used as a HART-USB modem, connected into the USB input of a PC, the modem does not need external power supply. The UNICOMM SAK-305 modules can be connected into a suitable device with RS485 interface input, used as a HART-RS485 modem. The communication protocol is HART on the RS485 line. In this case the device needs external power supply. The Ex versions can be connected to transmitters placed in hazardous areas
