D1400M
Modbus Modules with RTD Input
|
|
|
|
|
The
D1400M Modbus ADC module converts RTD 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
D1400M Modbus series modules can also be mounted on a DIN-Rail using the MK-1
mounting kit. |
