DNR-DIO-406
DNR-DIO-406
24-Channel Industrial Digital Input/Output Board for the PowerDNR RACKtangle®
 
The DNR-DIO-406 is a 24-channel digital I/O board packed with a number of unique features: as many as 24 DIO lines 350 V 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 external power (3.3-36 VDC). The DNR-DIO-406 layer is capable of continuously sinking 1 Amp per channel on all outputs, and provides readings on all inputs with available change-of-state detection.
 
Characteristics:
  • DNR-DIO-406 for use with RACKtangle™ I/O chassis
  • 12 digital inputs, 12 digital outputs (configured as current sinks)
  • Supports wide range of digital logic levels
  • I/O throughput rate of 100kS/sec
  • User-programmable hysteresis
  • Outputs provide drive capability of 1000 mA/channel (max peak - 1500mA)
  • Requires external 3.3-36V (24V nominal) power source or can be powered internally using the DNA-PC-912 power conversion layer
