Solid State Time Relay, Industrial Housing, 22.5mm, Screw Terminal, 16 Function, 2 CO Contact Elements, 0.05s–100h Time Range, AC/DC 24 100–127VAC Control Supply Voltage

This Siemens 3RP1505-1BQ30 solid-state time relay has 16 functions and an LED indicator, and can be operated with a control supply voltage of 24 VDC or from 100 to 127 VAC at 50 or 60 Hz. It is suitable for use in control, starting, protection, and regulation circuits and has screw connections for secure panel mounting. It has an operating temperature range of -25 to +60 degrees C, and its time intervals are adjustable from 0.05 seconds to 100 hours. Its functions include on and off delays, impulse on and off, pulse shaping, star-delta, and flasher. The relay's terminal has an Ingress Protection rating of IP20 for protection against access with a finger, and its front has an IP40 rating for protection against access by tools, screws, and wires. It is Underwriters Laboratories (UL) Listed, Canadian Standards Association (CSA) certified, and displays the European Conformity (CE) mark. This solid-state time relay is especially well suited for industrial control cabinets, power distribution boards, and control manufacturers.SpecificationsRelay typeTime, solid stateControl supply voltage and frequency24 VDC or 100 to 127 VAC at 50 or 60 HzOperating temperature range-25 to +60 degrees CTime adjustment range0.05 seconds to 100 hoursVibration resistance10 to 55 Hz/0.35 mmImpulse voltage resistance4,000VInsulation voltage300VPower consumption2WTerminal IPIP20Front IP ratingIP40Dimensions*102 x 22.5 x 91 mm (H x W x D)Standards metUL Listed, CSA certified, CE marked*H is height, the vertical distance from bottom to top; 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.
