Intelligent multi-point inspection device
Intelligent inspection instrument is suitable for 5~80 point process detection and alarm. Can input thermal resistance, thermocouple, DC current, DC voltage sensor, transmitter signal.
ø Basic error less than 0.2%F·S, display range -1999~9999
ø Set input signal type, range and alarm value for each channel
ø each channel d.u set digital filter time constant, effectively improve anti-interference ability
ø all channels d.u vertical setting zero and full correction, effectively reduce sensor error, improve the system measurement accuracy
► Any unused channel can be closed
► Level 2 parameters. Level 2 parameters are password controlled to prevent misoperation. With parameter copy function, greatly reduce the workload of parameter setting
ø D. U special practical alarm function, can be equipped with multi-point control unit to achieve the alarm output of each channel
► Manual, timing, alarm start printing
► Fast and effective communication interface, greatly shorten the communication time
Ii. Selection table of intelligent inspection instrument:
Note: the connection can realize the alarm output of each channel, each unit Z.UI 16 more control output, each table Z.ui 2 more 32 point control.
The multi-point control unit is used with the inspection instrument, through the supporting multi-point control unit, the alarm state of each channel can be output or combined output.
Achieve the purpose of alarm or control of each channel d.u.
Note :1. Standard configuration includes 4 points of control
2. All 16 control points can be selected as relay output or controlled solid state output, or different control outputs can be corresponding to different points, but it should be indicated when ordering.
