2-channel relay module 12V DC

Two-channel relay switching module 12V DC
Features:
The two-channel relay module is designed to control higher-power electrical circuits using 12V constant voltage control signals.
The module is suitable for security systems, access control devices, intercoms, gate automation, electric locks, alarm devices, lighting or other electrical devices.
The module is equipped with two independently controlled relays. When control voltage is applied to the input of the selected channel, the relay is activated and switches the output contacts. The common contact COM disconnects from the NC contact and connects to the NO contact. When the control voltage is removed, the relay returns to its original position. In this way, each channel allows a low-voltage signal to turn on, turn off or switch a separate electrical circuit.
Each channel is equipped with an LED indicator showing the status of the corresponding relay, and a replaceable fuse that helps protect the controlled circuit from excessive current.
The board uses two electromagnetic relays, each with one changeover contact. The maximum resistive contact load of each relay reaches 10A at 250V alternating or 30V direct voltage.
