DK178

Panel meters are widely used in industrial measurement and control systems to display or monitor processes, troubleshoot, and so on. The DK178 is one such panel meter with several advantages over other panel meters. Its compact size, low power consumption, and fast response time make it an attractive choice for many applications.

The DK178 takes a 4-20mA current input and converts it to a DC voltage output. This output is displayed on a 3-digit LCD display. The LCD can be customised according to the application, and is backlit for easy readability even in low light conditions. The DK178 also features an internal current/voltage protection circuit, and an over-range alert. These features are critical in preventing damage to the device or the connected equipment.

The DK178 has a wide range of applications. It can be used to measure analog signals such as pressure, temperature, current, and voltage. It is typically used in industrial automation systems, process control, and instrumentation systems. It is also widely used in automotive, medicial, and aerospace applications.

The working principle of the DK178 is simple. It uses an analog-to-digital converter to convert the 4-20mA current input into a digital signal. This signal is then filtered and amplified to adjust the level of the output voltage. The final output is then sent to the LCD display. The LCD display can be customised according to the application, and can be set to display a range of parameters such as pressure, temperature, current, or voltage. The device can also be used to output an alarm based on certain conditions, or to enable or disable certain functions.

In conclusion, the DK178 is an extremely versatile and reliable panel meter which can be used in a variety of applications. Its low power consumption, fast response time, and simple working principle make it a preferred choice for many industrial measurement and control systems. It can also be customised to display a range of parameters. The internal current/voltage protection circuit and the over-range alert further improve the safety of the connected system.
