Buy a 30 amp 2-channel and 5-channel power relay board or relay board that can be used in PLC input and output for further isolation and protection of PLC, HMI and other electronic equipment, suitable for industrial automation and smart home (smart building) or BMS projects. It has protective relay contacts against sparks caused by selfie and capacitive loads\r\n\r\nQuick and easy purchase link:\r\nhttps://taktatajhiz.com/\r\n\r\n\r\nProduct description:\r\n30 amp power relay card \r\nNumber of output channels: 2 channels and 5 channels\r\nExcitation voltage: 12 V and 24 V AC and DC\r\nCurrent of relays: 30 amps\r\nNumber of contacts: one\r\nRail installation\r\nOne year warranty\r\nCan be produced to order\r\n\r\n- It has an LED indicator of the disconnection or connection status of each channel\r\n- It has a diode to protect the return current of the relay and protect the sensitive electronic equipment of the panel such as PLC, sensors, etc.\r\n- Multifold increase in the life of relay contacts due to the use of spark arrestors and less spotting of relay contacts.\r\n- With detachable terminals\r\n- Installation in the electrical panel as a rail\r\n\r\n** Can be custom produced with your name, brand and contact information\r\n\r\nDescription:\r\nRelays and contactors are one of the most important and widely used equipment for disconnecting and connecting electrical current in electrical and industrial automation systems.\r\nIn the field of electricity and industrial automation, contactors are usually used to connect and disconnect high-power equipment or three-phase power loads, while relays are usually used in low-power control systems and to connect and disconnect single-phase currents. or lower DC voltages such as 24, 48, 60, etc., as well as isolation, protection and amplification of the output current of control and steering equipment are used.\r\nIn addition to connecting and disconnecting, relays are used as a device for isolation between two different potential sources and also as a power amplifier for the output voltage and current of the command circuit. By using a relay, it is possible to connect and disconnect equipment with a higher nominal current with a very weak control current.\r\nRelay card or relay board or relay board, due to the much lower price, easier installation on the rail, less volume of wiring and reduction of cost and time, quick and easy replacement of the entire board, occupying less space in the panel and... replace the relay and relay base have been railed. In this product, one coil end of the relays is connected from inside the board (jumper) and there is no need for additional wiring and use of jumpers.\r\nIn this product, a separate diode bridge is installed for each relay channel. This feature makes it possible to use relays both as zero common and one common (NPN and PNP) in the board\'s relay command input. Also, each relay is installed on a separate socket, which makes it possible to replace it easily in case of possible failure of any of the relays. Another important feature of this relay card is the use of detachable terminals in the inputs and outputs of the board.\r\nTo choose the right board relay for your desired application, you should look at the various characteristics of the relay card, such as the brand of the relay used, the number of relay channels, the excitation voltage of the relay coil, the current of contacts, the number
