DNR-DIO-406 United Electronic Industries 24-Channel Industrial Digital Input / Output Board

The United Electronic Industries DNA/DNR-DIO-406 24-Channel Industrial Digital Input / Output Boards are compatible with UEI's "Cube" and RACKtangle I/O chassis respectively. The DNA/DNR-DIO-406 is packed with a number of unique features: as many as 24 DIO lines 350V RMS isolated as a group, pre-configured with 12 inputs and 12 outputs, powerful user-programmable hysteresis that improves noise immunity of the digital input signals. The unit requires either external power (3.3-36VDC) or the installation of the DNA-PC-912, 24VDC power source. The DNA-DIO-406 layer is capable of continuously sinking 1 Amp per channel on all outputs, and provides readings on all inputs with manufactured change-of-state detection.

Outputs feature low impedance FET transistors that are configured in a "low-side" mode (logic 1 connects output to the DGND via FET, logic low keeps output floating), user loads should be connected between VCC and the output. This layer is also capable of driving solenoids - output FET transistor has a reverse protection diode, for extra protection it is recommended to add a reverse diode directly at the inductive load. DNA-DIO-406 has a maximum update rate of 100kS/s. The DNA/DNR-DIO-406 boards are an ideal digital I/O interface in a wide variety of PC based data acquisition, data logging and industrial control applications.
