DC Relays

A relay is a switch which can be controlled through a digital signal. There are 3 separate terminals in this relay: NO (Normal Open), COM (Common), NC (Normal Closed).

A relay is a switch which can be controlled through a digital signal. This is a 8 Channel DC relay module, each relay channel has 3 separate terminal, NO (Normal Open), COM (Common), NC (Normal Closed).

These are massive single pole double throw (SPDT) sealed relays. This means that when current is applied to the coil it throws a simple changeover switch, terminating the connection from the NC contact to ground and closing the NO contact. These relays can be used to switch high voltage/high current devices.

A relay is a switch which can be controlled through a digital signal. This is a 4 channel DC relay module which can each be controlled independently with a 315MHz latching RF remote.

This is a temperature controlled DC relay, where the relay can be set to turn on/off when the temperature reach higher/lower than the desired base temperature. You can set the base temperature by adjusting the onboard potentiometer. There is also a LED indicator to show you when the temperature is higher/lower than base amount.

This module is based on 2-Coil Latching Relay. Contrast to the ordinary relay, this latching relay do not need continuous power to keep the state, only a rising/falling pulse is needed to change the work state. Even the power can be removed when the work state do not need to change, making this module especially suitable for low-power projects.

These are massive single pole – single throw (SPST) sealed relays. This means that when current is applied to the coil it throws a simple changeover switch, terminating the connection from the NC contact to ground and closing the NO contact. These relays can be used to switch high voltage/high current devices.

A relay is a switch which can be controlled through a digital signal. This is a board mount DPDT DC mechanic relay. There are 2 separate channels, each channel has NO (Normal Open), COM (Common), NC (Normal Closed) terminals.

These are high quality Single Pole – Double Throw (SPDT) sealed relays. Use them to switch high voltage, and/or high current devices. This relay s coil is rated up to 12V, with a minimum switching voltage of 5V. The contacts are rated up to 5A (@250VAC, 30VDC).
