2 Channel 12V Relay Module Outputs that are transmitted by a relay: The standard relay interface that is typically open. Introducing COM, or Common Interface Relays. The typical relay interface used is a normally closed one. The material being used is metal. The 2 Channel 12V Relay Module provides a detailed overview of its content. 2 Channel 12V Relay Module utilizes authentic high-quality relays, featuring normally open interfaces and a maximum load of 10A at AC 250V or DC 30V. By employing SMD optocoupler isolation, this device offers strong driving capability and reliable performance. Additionally, it requires a low trigger current of 5mA. The operating voltage for this module is 12V. The 2 Channel 12V Relay Module voltage level can be adjusted by using a jumper setting to trigger either a high or low mode. In the event of a broken control line, the relay will remain non-operative due to its fault-tolerant design. The green power indicator and the red relay status indicator. The user-friendly design of human nature enables access to all interfaces through a direct connection terminal, providing great convenience. DC: power supply with a positive voltage output (VCC) The power supply for DC is negative (GND). A control relay can operate at either a high or low level. Whether you prefer a high or low lever is entirely up to personal preference. Trigger options are available at both high and low levels. A low level trigger occurs when the jumper is connected to the LOW pin. When the jumper is connected to the HIGH pin, it triggers at a high level.
