Description
The TSD2 Series is designed for more demanding commercial and industrial applications where small size and accurate performance are 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 TSD Series 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 (Interval) Upon application of input voltage, the time delay begins. The output is energized during the time delay. At the end of the time delay, the output de-energizes and remains de-energized until input voltage is removed. Reset: Removing input voltage resets the time delay and output. 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 Accessories P1004-95, P1004-95-X Versa-Pot Panel mountable, industrial potentiometer recommended for remote time delay adjustment.
