Intelligent inspection instrument is suitable for detection and alarm of 5~80 points process quantity. Input thermal resistance, thermocouple, DC current, DC voltage and other sensors, transmitter signals.

The basic error is less than 0.2%F·S, the display range is -1999~9999 weight

Input signal type, range and alarm value for each channel

The digital filtering time constant is set for each channel d.u, which can improve the anti-interference ability effectively

ø Zero and full correction for each channel d.u, effectively reduce the sensor error and improve the measuring accuracy of the system

► The unused channel can be closed at will

► Level 2 parameters Level 2 parameter is controlled by password to prevent misoperation. With parameter replication function, greatly reduce the workload of parameter setting

ø d.u practical alarm function, can be equipped with multi-point control unit to realize the alarm output of each channel

ø Manual, timing, alarm start printing

► Fast and effective communication interface, which greatly reduces communication time

2. Selection table of intelligent inspection instrument:

Note: The connection can realize the alarm output of each channel, with more than 16 z.u control output of each unit, and more than 2 z.u control points of each table to realize 32 control points.

The multi-point control unit is equipped with the inspection instrument. Through the supporting multi-point control unit, the alarm state of each channel can be output or combined output.

To achieve the purpose of alarm or control of each channel.

Note :1. The standard configuration includes 4 controls

2. All 16 control points can be selected as relay output or solid state output, or different control outputs can be corresponding to different control outputs, but it should be indicated when ordering.
