Whisker.Block
®
, Dual Dry Contacts & 4-20 mA Analog Inputs
D6 Labs Whisker-Block_3qtr-View_01
General Description
A long-range, 900 MHz, wireless sensor in a durable, transulcent
IP67 case with LED feedback, including four external input channels
for connecting two dry contact sensors and two 420 mA analog
sensors. The external sensors come pre-fastened to the included
wire bundles that connect to the Whisker.Block
®
via M8 connectors.
Also included is an internal, on-board, thermistor with +/- 1°C
accuracy. By default, readings are taken every five minutes and
battery life will last over ten years on the included battery pack.
Power
This Whisker.Block
®
can be powered internally using a 3.7V, 5.2A-H
LiThCl battery pack (10+ years of service life) or 8-24V DC through
Connector 1 pin 1. Select variants are equipped with an internal
5V/18V sensor power supply that can provide up to 30mA to
external sensors; this is available on pin 1 on both connectors when
battery power is used and pin 1 of connector 2 when external DC
power is used.
Range
In an unobstructed, outdoor line-of-site environment, the sensor
should be able to communicate for more than
.8 kilometers
assuming a receiving antenna elevation of
3.0 meters
. If the
receiving antenna is raised to
6 meters
or more, the range should
increase to more than
1.6 kilometers
. Range performance will
degrade if the internal antenna is used; maximum range is achieved
with the external antenna.
