DEI1184 8CH PROGRAMMABLE DISCRETE INTERFACE W/ EXT HV PROTECTION

Model No.: DEI1184

DEI1184-SES/SMS

Eight discrete inputs
Individually configurable as either GND/OPEN or 28V/OPEN (or 28V/GND) format input.
Input threshold and hysteresis per Airbus ABD0100H specification.
GND/OPEN mode: 4.5 V / 10.5 V input levels, 3 V hysteresis
28V/OPEN mode: 6 V / 12 V input levels, 3V hysteresis
1mA input current to prevent dry relay contacts.
Internal isolation diode in GND/OPEN mode.
Uses external series 3 kÃ´_Ã• resistors on inputs to implement lightning transient immunity of DO160, Section 22
