DNx-DIO-462-800, DNA-DIO-462-800, DNR-DIO-462-800, DNF-DIO-462-800

The DNx-DIO-462-800 are 12-channel, electromechanical relay boards. Based on UEI’s popular DNx-DIO-462, the DIO-462-800 is specifically designed for maintenance trainer applications or other applications which require “off” impedance greater than 100 MegOhm. (The standard DIO-462 “off” impedance spec is > 2 MegOhm.)

DNx-DIO-462-800 relays are in a Form C (SPDT) configuration and are rated for continuous operation at 2 A at 30 VDC, and 0.75 Amp at 125 VAC. Contacts are rated for 10 million operations. The board provides an ON resistance of less than 200 milliohms and update rates up to 125 Hz.

As part of UEI’s Guardian series boards, the DIO-462-800 not only controls the relay outputs, it also provides a powerful output monitoring capability. An on-board A/D converter allows you to monitor AC or DC output current. This allows the application to detect short and open circuits as well as other “suspicious behavior”. The monitoring capability is also a powerful diagnostic tool that allows a repair technician to quickly and accurately identify damaged or mis-wired channels.

The Guardian advantage also includes programmable overcurrent protection. The user may select the overload current up to one second before the channel is shut down. Each board provides 350 Vrms isolation between channels, as well as between the board, chassis and other installed I/O boards.
