PT7V40283-A2-2WF

PT7V40283-A2-2WF is a Class I Division 2 certified programmable timer/oscillator. This versatile device can be programmed to provide virtually any periodic output waveform or pulse train. Besides its flexibility in a direct replacement for existing parts, the main benefit of the PT7V40283-A2-2WF is its high level of accuracies and reliabilities that meet the industry need.

The application of PT7V40283-A2-2WF varies from time, frequency to time interval measurement tasks, such as timing for circuit, interval timing control, frequency division, time delay control and alarm system. PT7V40283-A2-2WF is widely accepted in process control, machine tool industry, water and wastewater treatment field, building automation, and telecommunications.

The PT7V40283-A2-2WF operates in two modes, cyclic and one-shot. Cyclic mode activates at the beginning of each cycle and turns off a predetermined amount of time later. One-shot mode remains active for a predetermined length of time and then resets to the beginning of the cycle. The internal oscilator frequency or a external input is used to program the unit.

The PT7V40283-A2-2WF is powered by a DC source. The input voltage can be varied from 12 to 24 volts and a minimum of 10 volts to activate the device. On power-up, the device reads and stores program parameters from an external memory device. The device can be programmed for up to 8 independent time channels and an unlimited number of timers can be controlled with one single device.

The working principle of PT7V40283-A2-2WF is simple yet effective. The external input is used to program the device. The device reads and stores the parameters from an external memory device and cycles according to the programmed parameters. When the input signal is received, the timer will start to count and the output signal will be generated according to the programmed parameters. When the programmed period is finished, the timer will reset itself and start a new cycle.

Overall, the PT7V40283-A2-2WF is a reliable and accurate programmable timer/oscillator device that can be widely used in different fields. It is Class I Division 2 certified and widely used in process control, machine tool industry, water and wastewater treatment field, building automation, and telecommunications.
