This gives a total maximum possible inputs of 10 per sensorProbe2D by utilizing both of the RJ45 sensor ports. These dry-contact ports can be used to monitor any dry-contact inputs, just like the normal autosense dry-contact ports, but, these ports can only be set to operate in the input mode.These additional sensors are labeled as ports 3 to 12.     Specifications & Features: Measurement range - Alarm or Normal Communications cable - RJ-45 jack to sensor using UTP Cat 5 wire Sensor type - open/closed contact switch Input voltage range. 0 to 5 volts Normal input voltage is settable under software Normally open, normally closed is settable under software Power source: powered by the sensorProbe. No additional power needed Measurement rate - multiple readings every second Up to 5 dry contact inputs per RJ-45 making upto 10 dry contact inputs in sensorProbe2.
