Timing Relay, On Delay Function, 0.05s-100h Time Setting Range, 12–240VAC/DC Control Voltage

This Siemens 7PV1518-1AW30 timing relay is a control relay with built-in time delay for controlling an event based on time. It has an LED indicator for monitoring operation status and screw-type terminals. This timing relay is Underwriter's Laboratories (UL) Recognized for safety, European Conformity (CE) and International Electrotechnical Commission (IEC) certified for quality assurance, and Ingress Protection (IP) rated for safety.SpecificationsControl voltageAC/DC 12-240 VCoil resistance4,000VTime setting range0.05 sec – 100 hourMountingSnap-on fastening on 35 mm standard railOperating temperature-25 to +55 degrees CDimensions*90 x 17.5 x 66.7 mm (H x W x D)Standards metUL (Underwriter's Laboratories)IEC (International Electrotechnical Commission)Ingress protectionFront: IP 40Terminal: IP 20*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system. Siemens manufactures electronic products for building automation, industrial drives, lighting, energy generation, medical equipment, and rail transportation. The company, founded in 1847 and headquartered in Munich, Germany, meets International Standards Organization (ISO) standards 14001, 9001 and TS 16949.
