RM2W Wireless Relay Module 2 Channel with ESP-12F

Description

RM2W Wireless Relay Module 2 Channel with ESP-12F The RM2W is a 2-channel Wi-Fi module based on the ESP-12F module which is based on the ESP8266 chip from Espressif. The ESP-12F includes 4MB of flash and supports 802.11b/g/n Wi-Fi SOC. The ESP-12F can be programmed serially via the 4-pin header. The card is well-protected, filtered, and easy to install. The RM2W outputs can drive loads up to 10A (resistive load). Features Based on ESP-12F Wi-Fi module. On-board 3.3V regulator AMS1117-3.3V. Power input is filtered for noise reduction. Green LED for power indication. Operating voltage DC12V. Two output relays with red LED indicators. Both normal open and normal close terminals are available. Output terminals are available through a 5mm 2-pin K128 screw clamp. Easy firmware uploading using a 4-pin header ( 3.3V, Tx, Rx, GND ). Reset push button switch is included. Two yellow LEDs for Tx and Rx signal indication. DIN Rail mountable. Four (Ø 3.5mm) mounting holes for easy installation. Dimensions: 98 X 50 X 18mm.
