2-Channel Relay Switching Board 12V DC

Dual Relay Switching Board 12V DC
 Features: The dual-channel relay module is designed to control higher-power electrical circuits using 12V DC control signals. The module is suitable for security systems, access control devices, intercom systems, gate automation, electric locks, alarm systems, lighting and other electrical control applications. The module is equipped with two independently controlled relays. When a control voltage is applied to the input of the selected channel, the corresponding relay is energized and switches the output contacts. The common (COM) contact disconnects from the normally closed (NC) contact and connects to the normally open (NO) contact. When the control voltage is removed, the relay returns to its default position. This allows each channel to switch, connect or disconnect a separate electrical circuit using a low-voltage control signal. Each channel features an LED indicator showing the corresponding relay status and a replaceable fuse that helps protect the controlled circuit against overcurrent. The board is equipped with two electromagnetic relays, each with one changeover contact. The maximum resistive contact load of each relay is 10A at 250V AC or 10A at 30V DC.
