D5400M
Thermistor Inputs
|
|
|
|
| The DGH D5400M
Modbus ADC series four channel thermistor input product line
converts up to four thermistor signals to digital information, linearizes the
digital data and communicates the values to a host computer or PLC. The
linearized digital data values are user scaleable in either degrees C or degrees
F.
The
data values are transmitted to a host computer via an RS-232 or RS-485
serial communications link using either the DGH ASCII protocol or Modbus
RTU binary protocol. The protocol is user-selectable.
Because the Modbus
RTU protocol does not support echoing, the RS232 versions of D5400M series
are limited to one ADC per serial port. Applications requiring more than
four ADC channels should use RS485.
The
D5400M series modules can also be mounted on a DIN-Rail using the MK-1
mounting kit.
