National Instruments SCC-CO20 Isolated Current Output Module

The SCC-CO20 (Part Number: 777459-33) is an Isolated Current Output Module from National Instruments. The instrument comes with a single channel at the output and is a low budget solution for economical users. The National Instruments SCC-CO20 Isolated Current Output Module supports the input voltage range from 0 to 10 volts. The output current range offered by the module is 0 to 20 mA. The module offers variable resistance for various load points and ranges from 2500 to 625 ohms for the load range of 5 mA to 20 mA respectively. This enables the user to fulfill various testing procedures.

The NI SCC-CO20 Module provides an absolute accuracy value of 0.1 % for the output range, up to full-scale. The typical value of temperature drift for the device is 0.5 µA per degrees Celsius, with the maximum value of 1 µA per degrees Celsius. The SCC-CO20 is easily portable, since it weighs approximately 28 grams. The physical dimensions of the module are 3.55 W x 7.93 L x 1.87 D cm.

The National Instruments SCC-CO20 Isolated Current Output Module also has voltage isolation options, with the capability to bear continuous 60 VDC for the channel to earth isolation. The value of current at the output of the module is proportional to the input voltage. It also makes use of an E/M Series DAQ device for this purpose. For maximum efficiency, the NI SCC-CO20 is meant to be used in the operational temperature range from 0 to 50 degrees Celsius.
