Netvox Wireless Multifunctional Control Box - 3 Dry Contact Inputs and 3 Dry Contact

The R831D is a Wireless Multifunctional Control Box device for Netvox Class C type devices based on the LoRaWAN open protocol and is compatible with the LoRaWAN protocol.

R831D is designed to control switch devices, mainly for electrical appliances. R831D allows you to connect and control 3 buttons and 3 dry contacts. The connected buttons and dry contacts will not affect each other. It will report 3 relay status and 3 input status.

R831D have three relay switches(output) and three dry contacts(input).

R831D can report status of 3 dry contacts individually and control 3 relays
