They are used in place of electrical timers, where the use of electricity is either unavailable or unsafe, such as applications in which flammable materials are present. The biggest problem with pneumatic timers and inert gases is that gases escape into the atmosphere. There is always a consistent leak of these gases, so you will have to replace these gases. Using compressed air is a much more economical endeavor. PRT Pneumatic Time Delay Relays. The Time Delay Relay delays a maintained input signal during an adjustable time period after which a regenerated output appears. Delay is set by turning knob. One 360° turn covers complete timing range. When white line on dial is set at top dead center, TDR goes to infinity. Analog Timers: The analog timers are those timers that are set up by knobs and their output is observed with an analog scale. ... Digital Timers: Digital timers are adjusted and controlled with the help of digital inputs and their output is also observed with the digital scales. In the simplest terms, pneumatic pressure controls move pressurized or compressed air “signals” from a controller to a device through copper or plastic tubes. Pneumatic controls stand in contrast to electronic controls, which send and receive electric or electronic signals. Pneumatic timers are typically used where no electrical power is available within purely pneumatic systems or often sited where electrical power is likely to be dangerous; pneumatic timers are considered intrinsically safe within these areas.https://seller.indiamart.com/product/manageproducts/

This method has easy way of controlling the device. If the push button is pressed, the contactor gets energised and gets closed. MK 1 DOL STARTER ARE IN DIFFERENT HP / RELAY RANGE. RELAY RANGES : 1A / 1.6A/ 2.5A/ 4A/ 6.5A/ 10A/ 14A. A 3 phase induction motor derives its name from the fact that the rotor current is induced by the magnetic field, instead of electrical connections. The operating principle of a 3 phase induction motor is based on the production of a rotating magnetic field (r.m.f.). Motor Full Load Current (Line) = (5×0.746)x1000/1.732×415 = 6 Amp. Motor Starting Current = 6 to 7xFull Load Current A DOL starter (also known as a direct on line starter or across the line starter) is a method of starting a 3 phase induction motor. In a DOL Starter, an induction motor is connected directly across its 3-phase supply, and the DOL starter applies the full line voltage to the motor terminals To properly size a NEMA-style full-voltage, across-the-line motor starter, the only information required is the motor horsepower and voltage. Sizing an IEC starter of the same type requires knowing the motor load, the duty cycle and full load current. NEMA standards list 10 sizes to cover 2-hp to 900-hp motors. Although typical control relays operate in the 5 ms to 20 ms range, relays with switching speeds as fast as 100 μs are available. Reed relays which are actuated by low currents and switch fast are suitable for controlling small currents.
