DT9853 / DT9854

The DT9853 and DT9854 are low cost analog output and digital I/O modules for the USB bus. These modules provide 4 or 8 analog outputs at 16-bit resolution in a compact, rugged enclosure. Each module is fully isolated to ±300V to protect your computer and maintain signal integrity, and are ideal for applications requiring stable and accurate output signals.

Key Features:

• 4 or 8 glitchless analog output channels with 16-bit resolution
• Galvanically isolated to ± 300V to protect your computer and maintain signal integrity
• 8 dedicated digital input lines and 8 dedicated digital output lines
• Interrupt on change support on up to 7 digital inputs – great for monitoring and controlling critical signals
• Output ranges of 0-10V, ±10V, and 0-20mA for maximum flexibility
• Scalable design – easily connect multiple modules together for high-channel count applications
• One, 32-bit counter/timer for counting external events
• Compatible with 8 to 36 VDC external excitation for current drive
• Configurable digital input state – choose either pull-up or pull-down
• Compact, rugged enclosure with standard screw terminal connections for easy wiring

The DT9853/54 can withstand an 8,000V spike directly to any pin without disrupting the module operation. The scope output above shows such a test.
