R831D-Wireless Multifunctional Control Box

R831D have three relay switches(output) and three dry contacts(input).
R831D can report status of 3 dry contacts individually and control 3 relays.

R831 can be equipped with a three-way controllable relay switch. The three-way relay output can be used as a dry contact. The user can separately control it through wireless commands which adopts SX1276 wireless communication module. R831 series has 4 types: R831A, R831B, R831C, and R831D. R831D reports the relay status and determines which relay to control through the network linkage and the instruction.
