Littelfuse TS1423 - The TS1 Series offers proven reliability and performance with years of use in OEM equipment and commercial applications. This encapsulated general use timing module is capable of controlling load currents ranging from 5mA to 1A. May be connected in series with contactors, relays, valves, solenoids, small motors, and lamps. Operation (Delay-on-Make): Upon application of input voltage, the time delay begins. The output is de-energized before and during the time delay. At the end of the time delay, the output energizes and remains energized until input voltage is removed. Reset: Removing input voltage resets the time delay and output.

Overview

The Littelfuse TS1423 TS1 Series Timing Module represents a cornerstone of reliable industrial automation, offering proven performance honed over years of integration into OEM equipment and demanding commercial applications. Engineered for versatility, this encapsulated general-use timing module is designed to precisely control a wide spectrum of load currents, ranging from a sensitive 5mA up to a robust 1A. Its robust construction and dependable operation make it an indispensable component for a multitude of control circuits. At its core, the TS1423 operates on a Delay-On-Make (DOM) principle, a critical function for sequential operations where a specific delay is required before a circuit is energized. Upon the application of input voltage, the internal timing sequence commences. Crucially, the output remains de-energized both before and throughout this programmed delay period, ensuring that downstream components are not activated prematurely. Once the preset time delay elapses, the output energizes and maintains its energized state until the input voltage is intentionally removed. This controlled energization is vital for applications requiring precise timing, such as sequencing motor starts, activating pneumatic valves after a system pressurization, or controlling illumination sequences. The reset functionality of the TS1423 is equally straightforward and dependable. The removal of input voltage immediately halts the timing sequence and de-energizes the output, returning the module to its initial state. This automatic reset mechanism simplifies system design and ensures consistent, repeatable operation cycle after cycle, minimizing the risk of unintended circuit states. This feature is particularly beneficial in systems that undergo frequent power cycling or require a clean restart. This timing module is exceptionally well-suited for integration in series with a variety of industrial components. Its current handling capabilities make it an ideal choice for controlling: * **Contactors and Relays:** Ensuring proper sequencing and preventing premature activation of larger power circuits. * **Valves and Solenoids:** Precisely timing the opening or closing of fluid or pneumatic control elements. * **Small Motors:** Managing start-up sequences or controlling intermittent motor operation. * **Lamps and Indicator Lights:** Implementing timed illumination or signaling sequences. The TS1 Series, exemplified by the TS1423, is recognized for its inherent reliability and cost-effectiveness, making it a preferred choice for engineers seeking robust and predictable timing solutions. Littelfuse, a globally respected leader in circuit protection and control, brings its extensive expertise to bear in the design and manufacture of these modules, assuring users of quality and longevity. The encapsulated design further enhances durability, protecting the internal circuitry from environmental contaminants, dust, and moisture, which is a significant advantage in harsh industrial settings. Selecting the TS1423 means investing in a time-tested component that contributes to the overall efficiency, safety, and reliability of your automated systems.
