Description
Surface Data Acquisition Cards are designed to supply power to and communicate with the downhole gauge; a single card can interface with up to 4 permanent downhole gauges. The card converts received raw data signals from the gauge into pressure and temperature values; the data is transmitted via a RS485/232 Modbus RTU protocol to a local data gathering system. The cards are supplied in a single channel or multi-channel (up to 4) configuration.
