D1450M Modbus Modules with Thermistor Input
|
|
|
|
|
The
D1450M Modbus ADC module converts thermistor temperature sensor signals to digital
information, linearizes the digital data, scales the data and
communicates the values to a host computer or PLC. The data values are
transmitted in Modbus RTU protocol to a host computer via RS232 or RS485 .
Because
the Modbus protocol does not support Echoing the RS232 versions of D1000M
series are limited to one ADC per serial port.
Applications requiring more than one channel should use RS485.
The
D1450M Modbus series modules can also be mounted on a DIN-Rail using the MK-1
mounting kit. |
