Panel indicators, pilot lights, and modules provide indication of machine, process, and safety status on plant machinery and equipment. They are available in different sizes and colors and can be used to indicate the presence or absence of the flow of electricity, machinery running, and other conditions. While pilot lights can provide an indication of electrical flow, 464-NKR12H-CWO is a latching alarm relay module used for industrial functions.

Description

The 464-NKR12H-CWO is a high-performance latching alarm relay module used for industrial applications. It features two separate inputs, one for normally closed (NC) contacts and the other for normally open (NO) contacts. It also includes two relays, one that is operated by pressing a reset button and the other by actuating a switch. The module can be used to latch input signals from sensors, switches, logic circuits, and other devices to activate an alarm when a certain event takes place.

Features

• Two separate inputs (NC and NO)
• Two relays (one manual and one actuated by a switch)
• LED indicator lamps (green for power, red for alarm)
• Three levels of timing and latching control (Simple, Factored, and Delayed)
• Input and output terminals for AC or DC control functions

Applications

The 464-NKR12H-CWO latching alarm relay module is used in a variety of industrial applications, such as:

• Process control
• Manufacturing automation
• HVAC/R
• Sensors and switches
• Data acquisition
• Machine control
• Power monitoring

Working Principle

The 464-NKR12H-CWO latching alarm relay module works by using a latching relay that is turned on when an input signal is received. It will remain on, until the manual reset button is pressed. The input signals can be from NO (normally open) type or NC (normally closed) type contacts, and depending on the signal the relay will stay in it’s either latched or reset state.

Once the reset button is pressed, the signal will be locked out and the LED indicator will turn red, indicating an alarm has occurred. The module is commonly used in manufacturing process control, data acquisition, and machine control applications for activating an alarm or switching the power supply off.

Conclusion

The 464-NKR12H-CWO latching alarm relay module is a versatile panel indicator and pilot light that can be used in a variety of industrial applications. It is designed to latch input signals from sensors, switches, and logic circuits to activate alarms when a certain event takes place. It is a reliable and cost-effective solution for providing visual indication of machine, process, and safety status that is often seen in the panels of plants and machinery.
