D5100M Modbus RTU Voltage Input Module

$250.00

The D5100M Modbus four channel voltage input modules provide direct connection to four analog signals of the same input type with full scale input ranges from +/-100mV to +/-100Vdc.

The D5100M Modbus voltage input modules provide an isolated 15-bit measurement, analog to digital conversion and linearization of the digital data. The digital data values are scaled in 16-bit unsigned integer data format that represents a percentage of full scale. See the Modbus scaling example link below.

The digital data values are transmitted to a host computer using the Modbus RTU serial protocol via an RS-232 or RS-485 serial connection. The D5000M series supports up to 247 Modbus RTU devices on one RS-485 serial port. Since Modbus protocol does not support RS-232 echoing, D5000M series modules cannot be daisy-chained. This limits you to one module per RS-232 serial port.
