  • Applications include thermostatic controls, industrial systems, flow meters, consumer products, or any system in which discrete control or monitoring is necessary.

The 1-Wire Octal (8 channel) Discrete I/O device offers an innovative way to monitor and control up to 8 digital channels. Each of the 8 points may be an input or an output under program control. Each channel also includes an activity latch, a programmable pulled-down resistor and programmable high / low alarms.  Furthermore, channels 1 & 2 include 32 bit pulse counters. 

The Octal Discrete I/O also includes a LED, conditional search support and an optional latching relay. These features combine to offer a flexible system for monitoring and controlling numerous data points throughout a 1-Wire network in an efficient manner. The conditional search support allows a host adapter to quickly identify whether any alarm parameters have been met. The LED and optional latching relay can also be configured to behave in a variety of ways:

  • Activate when an alarm becomes active and automatically deactivate when the alarm is cleared.
  • Activate when within alarm parameters and deactivate when within normal range.
  • Independently controlled

The nearly instant automated responses made by the LED and optional relay allows appropriate reactions (activate fan/alarm siren/etc.) to occur before the monitoring application is even aware of an alarm. The Octal Discrete I/O has been designed to simplify the reading and controlling process; and therefore any general-purpose 1-Wire host adapter is able to read and control the discrete channels. All of the Octal Discrete's data is contained in three 32 byte memory pages being updated in real time. More details on the Octal Discrete is available within the User Manual.


* The maximum input voltage may be extended to 48 Volts by disabling the pull-down resistor.
