D6100 Voltage Input Module


The D6100 voltage input module contains seven differential inputs for measuring DC voltages. Six user-selectable input ranges are available from +/-25mV to +/-10Vdc, making them ideal for measuring a wide variety of industrial sensors and annunciators.  Each input channel can be programmed to measure any one of six ranges.

The module performs all signal conditioning, 16-bit analog to digital conversion, linearization and stores the result in a 16-bit unsigned integer format. The unsigned integer data values represent a percentage of the voltage input full scale range.

The data values are transmitted to any supervisory host computer that supports the Modbus RTU serial protocol.  See the links to a Modbus scaling example and product documentation below.
