Description
The TSD3411S is a solid-state ON/OFF recycling timer with the on time always equal to the off time. When time delay is changed by the RT , both the ON and the OFF periods are changed. The TSD Series is designed for more demanding commercial and industrial applications where small size, and accurate performance is required. The factory calibration for fixed time delays is within 1% of the target time delay. The repeat accuracy, under stable conditions, is 0.1% of the time delay. The TSD3411S is rated to operate over an extended temperature range. Time delays of 0.1 seconds to 100 hours are available. The output is rated 1A steady and 10A inrush. The modules are totally solid state and encapsulated to protect the electronic circuitry. Operation (Recycling Flasher - ON Time First) Upon application of input voltage, the output energizes and the T1, ON time begins. At the end of the ON time, the output de-energizes and the T2 OFF time begins. At the end of the OFF time, the output energizes and the cycle repeats as long as input voltage is applied. Reset: Removing input voltage resets the output and time delays, and returns the sequence to the T1 ON time. Features & Benefits FEATURES BENEFITS Microcontroller based Repeat Accuracy + / - 0.1%, + / -1% time delay accuracy Extended temperature range Rated to 75°C operating temperature to withstand high heat applications. Compact, low cost design Allows flexiblility for OEM applications 1A Steady solid-state output, 10A inrush Provides 100 million operations in typical conditions. T otally solid state and encapsulated No moving parts to arc and wear out over time and encapsulated to protect against shock, vibration, and humidity Wiring Diagram RT is used when external adjustment is ordered.
