D1000M Analog Input Modbus Modules

 

The DGH D1000M series data acquisition modules use the Modbus RTU protocol for communication. The D1000M are complete single-channel data acquisition systems that are well suited to applications such as SCADA, data monitoring, data loggers, PLC’s, process controllers and instrumentation. The modules convert an analog input signal to engineering units and transmit in ASCII data format to any host or PLC with RS485 or RS232 serial ports. The D1000M Modbus DAS series analog signal input types include Voltage, Current, Temperature, Flow, Bridge and Load Cell.

The D1000M series converts the digital signal data into engineering units using look-up tables. The resultant data is stored in a memory buffer. The module’s ADC continuously converts data at the rate of 8 conversions per second and stores the latest result in the buffer.

Using RS485 up to 247 Modbus DAS modules may be linked to an RS485 port or PLC. Since Modbus protocol does not support echoing D1000M RS232 modules may not be daisy-chained. This limits you to one module per RS232 serial port. 

The four analog input D5000M Modbus DAS modules provide direct connection to four analog signals of the same type and range. ADC conversion and linearization of sensor input data and communicates in ASCII format via RS232 or RS485

DIN-100 Modbus series are low cost single channel modules that are DIN rail mountable.

Modbus Software Compatibility
 
The DGH Modbus I/O modules are compatible with all commercial software programs and OPC servers that support the Modbus RTU protocol. Commercials software programs from Wonderware, Intellution, National Instruments LabVIEW, and Dasylab all support the Modbus RTU protocol. 

OPC Servers from Kepware and MatrikonOPC support the Modbus RTU protocol and can be used to connect with other software programs.
