The Temperature Concentrator System (TCS) now allows the HART-to-Ethernet gateway system to work with the 16-channel temperature concentrator modules (TCM), enabling Ethernet-based communication with the TCS. The HART-to-Ethernet gateway comes in one or four-channel models with two TCMs able to connect to each channel. The four-channel gateway can connect with up to eight TCMs, allowing 128 temperature signals to flow over an Ethernet link to a Modbus/TCP host. The gateway system also has an embedded web server that allows temperature readings to be read with any standard web browser. This TCS update is also intrinsically safe for use in hazardous areas, further minimizing the need for dedicated hazardous-approved temperature transmitters.
