Get it by tomorrow, Aug 16. Low voltage on GPIO pin set as an output on ESP32 DEVKIT V1 Hey, I have issues with setting a 3V relay to high state as the voltage on pin 26, to which the relay is connected, is just 1V. Electronic monitoring relays in the EMD series are available for a wide range of monitoring tasks to avoid the consequences of errors or to keep them within limits.The operating states are indicated using colored LEDs, errors that may occur can be sent to a control system via a floating contact or can shut down a part of the system. Touch-Plate relays cannot be used to replace individual GE or Remcon relays. Voltages are used with a + or - 10% (so 0.33V fluctuation either side of 3.3V) and they are still within specification. A 3volt relay module (~150mA) draws certainly too much from 3.3volt VCC. There is a 3V version of the model you linked to. But this is not the case if your relays are the older GE or Remcon brand. 3v Relay Board for Raspberry Pi Arduino Relay Module 1 Channel Opto-Isolate High Level Trigger for IOT ESP8266 Microcontrollers Development Board, 10Pcs 1 Channel DC 3V/3.3V Relay Power Switch Module with Optocoupler Relay Module Isolated Drive Control Board for IOT ESP8266 Microcontrollers Development Board 3v Logic Level Boards, uxcell a12062900ux0221 DC 3V Coil 5 Pins SPST Power Relay JQC-3F 10pcs, 6PCS 1 Channel DC 3V Relay High Level Driver Module Optocoupler Relay Module Isolated Drive Control Board, Sponsored | Based on star rating and number of customer ratings, irhapsody Relay 12V, 5 Pin Relay, 40/30 AMP Automotive Relay Kit, Spdt 5 Prong 25 Pack 12-Volt Auto Relay Switch, Power Trim and Tilt Relay, irhapsody 5 Pack 40/30 AMP 12V DC Waterproof Relay and Harness - Heavy Duty 12 AWG Tinned Copper Wires, 5-PIN SPDT Automotive Relay, TWTADE/DC 12V Electromagnetic Power Coil Relay 10A 8 Pins 2DPT 2NO 2NC with Indicator Light and Socket Base -YJ2N-LY, Miniature Power Relay DC 12V HF41F/12-ZS 5 Pin 1NO 1NC 6A SPDT with LED Indicator with Socket Base 41F-1Z-C2 with DIN Rail Slotted 3Pcs (12VDC), mxuteuk 2pcs Electromagnetic Power Relay HH52P AC 110V/120V 5A Coil 8 Pin DPDT with LED Indicator, with Base Socket, with DIN Rail Slotted Aluminum, Cermant 2pcs 1 Channel DC 3V Relay High Level Driver Module Optocoupler Relay Module, LUOYIMAO General Purpose Relay 10 pcs DC 3V Coil 5 Pins SPST Power Relay JQC-3F, HiLetgo 2pcs SSR-40DA Solid State Relay Single Phase Semi-Conductor Relay Input 3-32V DC Output 24-380V AC.
