Product brief description
GE DS3800HHTB1D1D is an industrial automation module launched by General Electric(GE)designed for high-precision analog signal acquisition.Core functions include:
8-channel differential voltage input:Supports-1 to+1V DC range,15-bit resolution,slewing rate up to 7.5ms
Flexible power supply configuration:dual modes for backplane power supply and external power supply,compatible with GE Versamax series PLC
Anti-interference design:LED status indicator,5V output interface,support twisted pair cable grounding and optimized signal transmission
Product details
1.Hardware architecture and core components
Input channel characteristics:
8 independent differential input channels,using a software-configurable voltage range(-1V to+1V DC),supporting common sensor signals access in industrial sites.
Each channel is equipped with an independent converter,and the 15-bit resolution ensures±0.003%accuracy,which is suitable for high-precision measurement scenarios such as temperature and pressure.
Power supply and power supply:
Standard backplane power supply(+5V bus,current consumption 2mA),supports external power input,and is compatible with GE CPU 2.1 and above firmware.
Built-in overvoltage protection and power loss diagnosis function,and alarm is made through LED indicators when abnormalities are made.
2.Functional characteristics and industrial adaptability
Signal transmission optimization:
It is recommended to use twisted pair cable connection,and it is recommended to ground at the source device end to suppress common mode interference;if the source device is not grounded,grounding can be achieved through the built-in I/O terminal strip of the module.
Supports intermediate terminal expansion,which facilitates multi-device connection and maintenance.
Installation and cooling management:
Before installation,the physical status of the module should be checked to avoid abnormal performance due to mechanical damage;after installation,it is necessary to ensure reasonable heat dissipation design to prevent overheating from affecting the operation of other modules on the backplane.
