DNR-DIO-405
DNR-DIO-405
12-In/12-Out (opto-darlington) digital I/O board for the PowerDNR RACKtangle®
 
DNR-DIO-405 is a PowerDNR digital input/output board designed for low-speed, high-reliability isolated industrial digital I/O. DNR-DIO-405 features 12 digital input and 12 digital output channels, an I/O throughput rate of 1kHz and offers 350 Vrms isolation between layers. The layer is compatible with 5-36 V digital logic levels and can accept a wide range of user-supplied power (7 to 36 VDC).
 
Characteristics:
  • 12 digital inputs, 12 digital outputs (opto-darlington)
  • 5-36V logic levels
  • User-programmable hysteresis (on inputs)
  • 80mA per channel output drive capacity
  • Requires external 7-36V (24V nominal) power source or can be powered internally using the DNA-PC-912 power conversion layer
