The RJE-112DF is a general purpose non-latching 12VDC SPDT 5A 277VAC through hole relay manufactured by Wangrong. It is RoHS compliant, meaning it meets the Restriction of Hazardous Substances (RoHS) standards that relate to limiting the usage of hazardous materials in electrical and electronic equipment. This is a double-throw (SPDT) relay which can carry up to 5A of current through its contacts when operated at 277VAC. When de-energized, this relay has normally-open (NO) and normally-closed (NC) contacts, which can be used to create a circuit when it is energized. It features a manual override control switch, allowing users to switch the relay between its ON and OFF states when power is not available. It is also an insulated type of relay, meaning it is immune to shock, moisture, and other environmental conditions, making it suitable for use in harsh environments.
