The
D1100M Modbus ADC module converts
analog DC voltage signals to digital information, linearizes the digital
data, scales in millivolts 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 RTU 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
D1100M Modbus series modules can also be mounted on a DIN-Rail using the MK-1
mounting kit.
