The RM2N is a 2-channel wireless relay module based on the nRF24L01+ chip from Nordic Semiconductor. The nRF24L01 module is designed to operate in the global 2.4GHz ISM frequency band and uses GFSK modulation to transmit data. The card is well-protected, filtered, and easy to install. RM2N outputs can drive loads up to 10A (resistive loads).
Features:
Based on nRF24L01+ module.
On-board 3.3V,5V regulator.
Power input is filtered for noise reduction.
LED for power indication.
Operating voltage DC12V.
Two output relays with red LED indicators.
Both normal open and normal close terminals are available.
Relay outputs are available through 5mm 2-pin K128 screw clamp terminals.
Easy configuration and test.
Reset push button switch is included.
