D1100M MODBUS RTU Voltage Input Modules

D1100M Modbus Modules with Voltage Input

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.
