Signal relays are versatile devices that are used to control, protect, and even switch high-power signals. The 3SBC2018A2 is one such device and has been designed to be used in a variety of applications where the maximum signal size is two Amps or less.

The 3SBC2018A2 is an ideal solution for applications that need to manage signal sizes between two and twenty-four volts DC. The device can switch loads up to two Amps and features two Form C SPDT switches and a variety of LED indicators. The unit measures just 3” in length and 1.75” in width, making it top-notch for space-starved applications.

In terms of technical aspects, the 3SBC2018A2 has a 6.4mm double-ended relay coil with gold-plated contacts and a contact rating of up to 24V/2A DC. It has an on/off ratio of about 1:125 and a response time of approximately 0.75msec. The relay has a maximum surge current rating of 8A peak for 1/2 cycle, 5A for 10 cycle, and a maximum leakage current of 36mA at 5V. The device is also rated for 1.6 million mechanical operations and has a dielectric strength of 1000VAC between coil and contacts.

In terms of operating principle, the 3SBC2018A2 follows two distinct processes. The first process is the activation of the device. This process is initiated when a current is applied to the relay coil and ends when the contacts open or close. The second process is the deactivation procedure, which is activated when the current is removed from the relay coil and is completed when the contacts fully open or close.

In terms of durability, the 3SBC2018A2 is designed to withstand electro-magnetic interference due to its gold-plated contacts and can handle temperatures ranging from -20 to +85°C. It is UL, CUL, and RoHS compliant and carries the EN 60335-1:2011 Grade B safety approval.

Overall, the 3SBC2018A2 is an excellent signal relay that is suited for applications requiring a high current rating and small physical size. It is reliable and durable enough to handle any job, and its two Form C SPDT switches are designed to be incredibly user-friendly. The device is definitely worth a second look if you are looking for a signal relay that can handle up to two Amps of power.
