Industrial HC12-3 DC Coil Relay 12VDC 4A Contact Rating

Industrial HC12-3 DC coil relay with a 12 VDC coil and a 4 A contact rating. This relay is energized by a 12-volt direct current control signal and is designed to switch loads up to 4 amps on its contacts, making it suitable for interfacing low-voltage control logic with higher-current equipment in industrial automation and control panels. The HC12-3 provides galvanic isolation between the control and load circuits, helping protect control electronics and supporting reliable operation in typical industrial environments. Use it to convert a 12 V control signal into a separate, switchable contact path for loads that stay within the 4 A rating. When selecting this relay, verify that the coil voltage matches your control supply and that the connected load current does not exceed 4 A, with appropriate wiring practices and any required protection to maintain safe operation over its service life.
