PDC - Model DCI-90-242 -Dual Channel DC Isolator

The PDC Model DCI-90 dual channel DC isolator is designed specifically to meet the New York Department of Transportation, Model 242 specifications. Each channel ofthe DC isolator shall present a true signal (ground closure) at the output ofits optical coupling device when a contact closure causes an input voltage ofless than 8 VDC, for longer than 5 milliseconds. A transition from a true to a false signal at the output shall occur when the respective contact closure causes an input voltage ofgreater than 12 VDC. All electronics are provided on a single sided P.C. board with an aluminumfront panel. The P.C. board is provided with a solder mask, silk screen identifying all component locations and is conformally coated to resist adverse environmental conditions
