The FBQA7000 backup operator is functionally equivalent to an FBQA5000 intelligent backup operator and an FBB5000 digital display transmission instrument.

It receives 0~10mA/0~20mA/4~20mA/0~5V/1~5V valve position given input signals from DCS system or intelligent regulator, outputs 0~10mA/0~20mA/4~20mA/0~5V/1~5V valve position given output signals, and then drives the electric valve actuator by servo amplifier or drives the pneumatic diaphragm valve by electrical converter and valve position locator, and displays the valve position given output value on the main screen (upper screen) at 0~100%.

It simultaneously receives engineering quantity signals such as temperature/pressure/flow from the site, displays the workload value on the attached screen (lower screen), and transmits the engineering quantity output on the transmission output 2 for use by subsequent instruments or recorders.

Suitable for use as a backup operator for DCS system loop regulation control output and intelligent regulator control output.

When FBQA7000 is in automatic mode, its valve position given input and valve position given output are equivalent to direct flow, to achieve automatic control of valves by DCS system or regulator. But the signal format for valve position given input and valve position given output can be different. That is to say, it can simultaneously serve as a signal format converter.

※ Manual automatic seamless switching.

※ Remote manual automatic control.

※ The input and output signal buttons are optional.

※ Remote forced manual operation.

※ Can be equipped with RS485 isolated communication interface.

Intelligent design of microcontroller, all parameter buttons can be set, dual digital display, dual light column display (vertical meter).

FBBUS-ASCII code protocol and MODBUS-RTU protocol are optional (MODBUS-RTU protocol is only used for Modbus option, and the wiring method is the same as RS485).
