The Input Box (DIB) consists of a wireless monitoring module using the most advanced 2.4 HGz 802.15.4 communications protocols. It has 3 digital dry contact inputs and one analog input (future option). The DIB is a non-routing sleepy device.
The DIB is housed in an IP65 industrial box (IP66 for non-ATEX) and external antenna. It is powered by four 1/2 AA batteries type Tadiran TL4902 that power the unit for more than 8 years assuming not more than 10 input changes per hour. Whenever one of the inputs changes state, the DIB reports the state of the three dry contact inputs and the timing between the dry contact events.
