DIN-110 Modbus Voltage Input Modules


The DIN-100 voltage input modules contain an isolated 15-bit analog to digital converter and measure DC voltages with full scale input ranges from +/-10mV to +/-100Vdc. Each module is hardware optimized for the best measurement performance over a certain input range. Six different voltage input ranges are available.

The DIN-110 performs all signal conditioning, the analog to digital conversion and produces a linearized data output. The data values are scaled in 16-bit unsigned integer format that represents a percentage of the full scale input range. The data values are transmitted to a host computer using the Modbus RTU serial protocol via an RS-485 serial port.

The DIN-110 series remote I/O modules are compatible with all commercial software programs and OPC servers that support the Modbus RTU protocol. Commercials software programs from DreamReport, Wonderware, National Instruments Labview, Indusoft, DAQFactory and DASYLab all support the Modbus RTU protocol. OPC Servers from Kepware and MatrikonOPC support the Modbus RTU protocol.
