Time Delay Relays (TDRs) are generally used in control, instrumentation, and signal processing for a variety of applications. The 7012QKM is one such TDR, which has various features and applications. The 7012QKM offers a wide selection of on board features including a resistive output programming, resistor programmable timer circuit, adjustable operating time, self powered operation at 3.0 to 6.0 volts, and a power off defeat feature.

The 7012QKM is a TDR device with a dual timer circuit, which has the following type of operating mechanism. The first timer is activated by a resistive input, either an open or a closed switch, and the second timer is activated by a capacitor, either an internal or external capacitor. The resistive input and the capacitor are connected in series with the output terminals. This combination allows the 7012QKM to respond to changes in the input signal and then switch output terminals.

The 7012QKM is able to operate with a wide range of input signals, ranging from 0.1VAC to 53 VAC or 0.1VDC to 24VDC. In addition, the 7012QKM is also able to operate with a variety of output signals, ranging from 0.5 amp to 7.5 amps or 30mA to 500mA. This makes the 7012QKM suitable for a broad range of application, such as motor control, lighting control, process control, HVAC, and security systems.

Since the 7012QKM incorporates a resistive input programming, it is easier to adjust the on-state and off-state times. This can be done by changing resistance values in the resistive network. The 7012QKM allows for setting timers to any desired time periods ranging from 10ms to 10s. The timing range can also be extended further by adding external capacitors or resistors in the appropriate positions.

The 7012QKM also has a built in self powered feature. This feature allows the 7012QKM to be operated with 3.0 to 6.0 volts input power, if it cannot be connected to an independent power source. This is quite helpful in applications that have limited power supply. The self powering is done by using a combination of transistors and diodes.

The 7012QKM also has a power-off-defeat feature, which is quite useful in applications where the control input and the output terminals need to be isolated. This feature helps to prevent accidental activation of the 7012QKM when the power is off.

The 7012QKM is a time delay relay that can be used in a wide range of applications. It is easy to use and has a wide range of input and output signal levels. The 7012QKM is also self powered and has a power-off-defeat feature. This makes the 7012QKM an ideal choice for use in a variety of applications such as motor control, lighting control, process control, HVAC, and security systems.
