ZigBee module with 2 analogic inputs, 2 digital inputs and router

The ZR-AIAO-EM is a multifunction wireless sensor with: one 0-10Vdc analogue input, one 0-10Vdc analogue output, one NTC thermal temperature probe input and one digital input with pulse counting functionality.
This device can perform data transmissions automatically and immediately (regardless of configured sampling rate) in order to signal a status change in one of the two digital inputs.
The device is supplied continuously at 12-24 Vcc/Vac and can also act as a repeater or a “parent” device for battery-powered sensors.
