<p>PURPOSE: To obtain a general pressure measurement interface device which interfaces many pressure transmitters with a data gathering device. CONSTITUTION: This converter output interface device 12 interfaces DC driving pressure transmitters 10a, 10b, and 10c with the data gathering device 14 and data signals generated by the transmitters are sent to the data gathering device through multi-wire transmitter cables 30a, 30b, and 30c; and the interface device consists of multi-pin collectors 16a, 16b, and 16c for coupling the signals between the cables and interface device, a master pin connector 18 which couples the signals between the interface device and data gathering device, a power receiving module 22 which receives an input power signal of nearly 100-240V AC and 50-60Hz, a power source 20 which converts the input power into specific different DC voltages according to power conditions of the converter, and a means which couples the DC power with the multi-pin connector and supplies the DC power to the transmitters.</p> |
