NTI E-DI16DO16-D Digital Input/Output Expander (Open-Collector Outputs) DIN Mount

The E-DI16DO16-D Digital I/O Expander with Open-Collector Outputs adds 16 digital inputs and 16 digital open-collector outputs to an E-2D/5D/16D. Door switches, emergency / panic buttons and vibration sensors are some of the many digital input sensors that the expander supports. The 16 open-collector outputs can sink up to 500mA of current to control externally powered devices running on up to 24V DC, such as the Automatic Voice Dialer (runs on 9-18VDC), which is controlled by the ENVIROMUX system. For example, if a temperature sensor that is connected to the ENVIROMUX system detects that temperature has risen to critical levels, the ENVIROMUX system can activate the voice dialer connected to the expander to notify personnel of the issue.
