Isolated Analog Input Card (4 Channel)
The MSI-C420P Isolated Analog Input Card is designed for acquiring analog data in harsh electrical environments in STD BUS systems. The unit is particularly useful in RTU, SCADA, and monitoring and control applications. Commonly encountered ground loop currents and voltages and large common-mode voltages associated with industrial monitoring applications are eliminated by onboard circuitry. The unit provides four isolated 12-bit differential input channels with ±1 LSB conversion accuracy at rates up to 6,000 samples/second. Jumper selectable input ranges of 0-1V, 0-5V, 0-10V, ±5V, ±10V, 0-20 mA and 4-20 mA are available (other ranges on request). Active isolated 20 mA outputs are provided for powering transducer transmitters. Isolation voltage of 750V from input-to-input and from input-to-bus with a overvoltage of 100V at the input. The unit uses 16-bit I/O-mapped addressing with jumper selectable I/O addresses. Requires +5V only.
