D1600M Modbus Modules with Frequency Input
|
|
|
|
|
The
D1600M Modbus ADC module converts frequency and pulse 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
D1600M Modbus series modules can also be mounted on a DIN-Rail using the MK-1
mounting kit. |
