D-Wire Sensor
Track your environmentals with D-Wire Sensors

D-Wire sensors are a way to track environmentals in your server room (wide range temperature support: -40 to 180 degrees F), PBX closet, or data center using minimum analog capacity. With the TempDefender's D-Wire sensors, you don't have to worry about analog capacity on your RTUs, tangled masses of sensors at your RTU, or even the trouble of wiring analog connectors.

D-Wire sensors from DPS use simple RJ-11 connectors, in and out, and allow you to chain up to 16 sensors to a single TempDefender D-Wire port. Your sensor chain can run a maximum of 600 feet, so you can run sensors out as far as you need to monitor your equipment, without having to place analog-capable RTUs in multiple places. Note: Internal D-Wire sensors (for internal temperature or internal voltage monitoring, for example) impact total sensor cable length.

The maximum length of a D-Wire daisy chain varies depending on the number of sensor nodes in the chain. A single sensor can receive power and transmit data over 600 feet of wire (for example, 3 sensors could have lengths less than or equal to 200 feet). Adding sensors to the chain consumes more power and reduces the maximum allowable wire length, as described in the table below:

D-Wire Temp

Temperature Sensor. (D-PK-DSNSR-12001)

Temperature sensor that connects to the DPS Sensor network. This sensor can report live-analog values for monitoring temperature within +/-2 degrees F.


D-Wire Temp/Humidity

Temperature & Humidity Sensor. (D-PK-DSNSR-12002.00002)

Monitor temperature and humidity using the D-Wire Temperature and Humidity combination sensor. This device can accurately report the live-anlog values for temperature (+/- 2 degrees F) and humidity (+/0 4% RH).


D-Wire Temp w/ LED

Temperature Sensor w/ LED. (D-PK-DSNSR-12003)

An additional LED on this D-Wire Temperature Sensor gives a visual notification on the sensor. Much like the standard Temperature Sensor, this device will monitor live-analog values and can report temperature within +/- 2 degrees F of the actual value.


D-Wire Batt.Cell

Batt.Cell Voltage Sensor. (D-PK-DSNSR-12004)

Battery Voltage Monitor & Temperature Probe that connects into the DPS Sensor network. This sensor is ideal for the digital inputs located on the Battery Voltage Monitor G2. Battery voltage range options include: 0VDC - 5VDC, 0VDC - 12VDC, 0VDC - 16VDC, and 0VDC - 60VDC.


D-Wire External Sensor Probe

Temperature External Sensor Probe. (D-PK-DSNSR-12008)

External 8 foot temperature probe that is compatible with the DPS sensor network. This sensor may be plugged directly into a D-Wire point of a DPS RTU or may be the terminating point of a daisy chain of D-wire sensors. Note: This sensor probe is not daisy chainable.
