Foxboro system adopts controller FCP processing capacity up to one function module per second IO capacity up to one FBM processing capacity up to one processing function module configuration communication medium all adopts optical cable connection supporting redundant M optical cable connection. At the same time, FCP advanced fault-tolerant technology. Redundant cards do not need to exchange error messages without delay and without disturbance switching.

The Foxboro system has an LED indicator that measures current without disconnecting the wires. Convenient maintenance: signal circuit and power supply circuit with the Omni-directional safety fuse alarm and LED indicator, cooperate with the measuring signal current technology, clever the demolition could not measure the signal current as long as ammeter pens and insert test hole, the whole measurement process does not affect the normal process of measurement and control equipment, electric unceasingly, provides great convenience for maintenance work.

The Foxboro Smart Two-Wire Transmitter is fully protected by an overlaid HART digital signal and provides reliable, accurate absolute pressure measurements. The power loop adopts overcurrent, reverse connection protection, and overvoltage measures to ensure the safe operation of the system equipment. In order to provide a full range of security, each signal circuit is equipped with the insurance of convenient unplug, the user does not need to separate the safety terminal and distribution switch for the external equipment, so that you can not unplug the meter, omit the distribution switch, to avoid misoperation. Especially solve the PLC and DCS system foreign instrument stop meter, inspection, dismantling the external equipment as long as the unplug the insurance without taking out the wire, both safe and reliable, fast and efficient to prevent wrong connection.
