Guardian Series diagnostics
The DNx-DIO-462 are 12-channel, electromechanical relay boards. Relays are in a Form C (SPDT) configuration and are rated for continuous operation at 2A 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 DNx-DIO-462 not only controls the relay outputs, it also provides a powerful output monitoring capability. An onboard A/D converter allows you to monitor DC output voltages (relative to the common terminal) and 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.
UEI's Guardian Series brings system monitoring to a whole new level.
In this Master Class, UEI application engineer Austyn Turner walks through our sophisticated and reliable on-board monitoring diagnostics we call “Guardian”, also known as "Built-In-Test" or BIT.
