Relay with human body detection sensor (japan import)

  • Supply voltage range: DC9V ~ 20V (stabilization required)
  • Current consumption: standby; approximately 5mA operation; about 40mA (maximum)
  • Detection range: about 1m ~ 5m (variable) detection angle: up, down, left and right 20 (90%)
  • Timer set time / 35 seconds about 1 second to (variable: update type) relay contact capacity / maximum 3A-100V (AC) 3A over 28V (DC)
  • (At the time of completion, including projections) with feature detection brightness around, open collector output with, surge absorber with W75xD80xH36mm: size

sensor to determine the presence or absence of people to catch the infrared rays emitted by the human body. When the sensor reaction can be controlled electrical devices such as relays bulb base on the connection turned ON, and to the outside. In addition, the board is equipped with a light sensor to determine the brightness of the surroundings, can also use "and without the electric light connected during the day bright surroundings, to light only night was dark" and. Relay to operate the external device is turned-timer, this timer OFF. So-updating automatically after ON, timer time is extended sensor reacts before the relay is OFF, the while there are people You can leave ON the relay.

Joe asked Anyone help with any information due to these 3 phase phase faults?

Explain the operation of the protection system on a three phase transmission line in the event of a given common fault. Fuses, circuit breakers, over current relays and under voltage relays are used as protection devices to protect transmission lines, generators, transformers and loads on a 3 phase network. Describe the operation of such protection system in the event of the following faults: a.Phase to phase fault b.Phase to neutral fault

And got the following answer:

Ideally, a phase to phase fault would trigger opening of at least one phase. Phase to neutral would cause the affected phase to open. They might also reclose a few times. Fuses open on overcurrent, and usually have a melt curve approximately similar to the wire they protect. Circuit breakers can reclose. For small molded-case breakers, it is usually manual. Large substation breakers might reclose automatically, or by remote control Overcurrent relays sense too many amps going through a wire, and trigger a circuit breaker, disconnect, or interrupter of some type. Undervoltage relays sense low voltages (such as due to a short circuit) and may work together with overcurrent relays to build a more accurate picture of where a short might be, and which lines need to be isolated.

The over voltage relay function extremely nicely with various applications that are specific to power distribution and protection. The relays come with wide adjustment ranges with a scale that’s simple to read either in three or four digits in accordance with the model. These over voltage relay aid in escalating the flexibility in the applications, reduce the overall power and maintenance charges. There are actually relays which are employed for general purposes which come in reliable styles with speedy replacement alternatives. And there are actually models which can be applied for industrial applications and heavier duty applications that work on big loads. These products are produced to meet the lifetime industrial manage requirements of your applications.
Their most current products would be the Time counter, Timer Delay, over voltage relay, Rapid Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and different others. The web site delivers a detailed description of each and every model in many categories of over voltage relay couplings and sensors. These products are particularly useful for high-risk applications. The over voltage relay are also accessible with attributes like a number of timing ranges and functions. The firm is at present looking for agents and dealers who can promote and sell their factory produced products. They may be generally on a lookout for developing new and much more reputable merchandise depending on the requires and specifications of the industry.
