Time Delay Relays (TDRs) are a type of relay that is used to delay the activation of a device for a determined period. The TDR4B23 is a common Time Delay Relay used in industrial and residential applications. This article will explain the application field and working principle of the TDR4B23. The TDR4B23 is a versatile Time Delay Relay with a variety of potential applications. It can be used in industrial and residential settings; in industrial settings, it can be used to delay the start or stop of a cycle, such as in a pump or conveyor system, as well as to activate a safety system. It can also be used in HVAC systems, security systems, and lighting control systems to automate certain processes. In residential settings, the TDR4B23 can be used to control lighting, heating, and air conditioning systems. The TDR4B23 is a modular unit that contains three independent Delay ON functions, three independent Delay OFF functions, and one Start Delay function. It also has a built-in delay circuit that is adjustable from 0.5 to 999.9 seconds. The adjustable delay circuit is triggered by a switch input, and the output can be connected to an external load or switch. The TDR4B23 has two operating modes: time delay or periodic pulsing. In time delay mode, the output is delayed when the switch input is activated, and the output is delayed for the set time before being activated. In periodic pulsing mode, the relay will pulse the output based on a set number of pulses and delay time. The TDR4B23 is designed with safety in mind, so it’s protected from overvoltages and short circuits. It can operate in temperatures ranging from -20°C to +70°C, and has selectable output voltage of 6, 24, or 36 volts with a maximum current of 1 amp. It also has an LED indicator that lights up when the relay is activated. The TDR4B23 Time Delay Relay is a versatile unit that can be used in a variety of settings. It provides adjustable timing functions, and it is designed for safe operation. With its wide range of potential applications, the TDR4B23 is a reliable and practical choice for a variety of industrial and residential systems.
