CDB-38-70016 Industrial Controls

Time Delay Relays (TDRs)are are specialized relays that impose a time delay into a circuits. There is a wide variety of different TDRs on the market, each with its own features and function. One of the most commonly used TDRs is the CDB-38-70016. This relay has a variety of uses and applications, as well as a distinct working principle. The CDB-38-70016 TDR is a miniature, 4PDT relay that is ideal for controlling electrical loads in a variety of applications. This relay can be used to provide timing sequences in motor control applications, implementing motion control in machinery actuator systems, activating sprinkler systems, and controlling HVAC systems. It can also be used in gardening irrigation, parking system motors, lighting fixtures, and has also found use in industrial control systems and computer integrated manufacturing systems (CIMS). The TDR also works well in power systems and AC/DC motor control applications. The main function of the CDB-38-70016 TDR is to delay the operation of equipment at a predetermined time after the start of an application sequence. This means that the TDR will only activate after a certain period of time has elapsed. It can be adjusted to provide a delay of up to 30 minutes, with delays of 1 second, 1 minute, 30 minutes, and other increments being available. The working principle of the CDB-38-70016 TDR is based on a biphasic, electromechanical timer made up of two coils; one connected in series with the auxiliary contact, and the other in parallel with the contact. The relay coil is polarized and connected in series between the power supply and the working circuit. When current is applied, the first coil energizes, applying power to the contacts and switching them on. When the current is switched off, the relay coil becomes de-energized, the contacts can switch off at the predetermined timing and the second coil is energized. The CDB-38-70016 TDR is a reliable and versatile device for controlling electrical loads, with a wide range of applications and an effective working principle. Its biphasic timer provides precise control of the timing sequence, making it ideal for motor control applications and industrial systems. The compact design also makes it easy to install and use, making it an ideal choice for any project.
