DNR-DIO-402
DNR-DIO-402
24-channel digital output board for the PowerDNR RACKtangle®
 
The DNR-DIO-402 digital output board is designed for applications requiring relatively low-speed, high-reliability isolated industrial digital I/O. The board features 24 digital output channels, I/O throughput rate of 1kHz, and offers 350 Vrms isolation between layers. The layer can accept a wide range of user-supplied power sources ranging from 7 to 36 VDC.
 
Characteristics:
  • 24 digital outputs
  • 80mA per channel output drive capacity
  • I/O throughput rate of 1kS/s
  • Requires external 7-36V (24V nominal) power source or can use DNA-PC-912
