The versatile, multi-function DM8000 serves as a tachometer, counter, totalizer and zero speed switch–in a space saving 1/8 ...

An electrical relay switch is a solid-state or electromechanical switch that uses a low-power signal to operate a high-power circuit. It can switch currents electronically using semiconductor devices ...

Again, a small general-purpose DPDT relay with 5-VDC coil and 1-A contacts seemed like a flexible, risk-free way to address these issues. I connected the coil between the supply rail and active output ...

The relays used are commodity HK-19F DPDT relays, in 12-volt and 6-volt versions [Ref 12]. Figure 1 The magnetic field of the coils, shown as a dashed line, is an important part of the signal flow in ...

Even adding an LED to a relay as a coil-status indicator shows the options and tradeoffs that enter into the choice of solution.

Henry Engineering’s SuperLight is a logic/control interface for controlling low-voltage studio tally lights. It can directly power 12 V DC LED tally lights that draw up to 500 mA. SuperLight includes ...

The 120VAC, 10A-rated alternating relays, used to optimize load usage, are available in SPDT or DPDT configurations; an onboard switch selects alternating or single-load operation. The 120VAC pump ...

This ultra-compact and slim DPDT signal relay is fully sealed and conforms to North American Telcordia specifications (formerly Bellcore). The device also conforms to FCC Part 68 (i.e. impulse ...

Fig. 7 shows a DPDT relay having two switches controlled by one excitation signal. Switches with polarity of 12V are required for the motor. Direction of motion of the UGV changes accordingly. These ...
