The TAC1 Series was designed to delay the operation of a compressor relay. It eliminates the possibility of relay chatter due to half-wave failure of the output. It connects in series with the load relay coil and provides a delay-on-make time delay each time input voltage is applied. It can be used for random start, anti-short cycling, sequencing, and many other applications. It is an excellent choice for all air conditioning and refrigeration equipment. 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 Time Delay Type Analog circuitry Range 0.05 - 600s in 4 adjustable ranges or fixed Repeat Accuracy ±2% Tolerance (Factory Calibration) ±20% Recycle Time ≤ 20ms after timing, during timing - 0.1% of time delay or 75ms, whichever is greater Time Delay vs Temp. & Voltage ≤ ±10% Input Voltage 24, 120, or 230VAC Tolerance ±20% AC Line Frequency 50/60 Hz Output Type Solid state Form NO, open during timing Rating 0.5A steady state, 10A inrush at 60°C Voltage Drop 120 & 230VAC: ≅ 4.2V @ 0.5A24VAC: ≅ 2.5V @ 0.5A Protection Circuitry Encapsulated Dielectric Breakdown ≥ 2000V RMS terminals to mounting surface Insulation Resistance ≥ 100 MΩ Mechanical Mounting Surface mount with one #10 (M5 x 0.8) screw Dimensions H 50.8 mm (2”); W 50.8 mm (2”);D 30.7 mm (1.21”) Termination 0.25 in.
