Analog Wall Switch 1 Button

Description

Datasheet

The NS210 1 Button Wall Switch is a versatile low voltage analog wall control designed for easy integration into existing building control systems. Connect the wall switch output signal to an analog input of a controller, gateway, or data acquisition unit. The analog voltage level indicates which button is pressed.

Key Features:

• Single Tactile Button: The button drives the analog output voltage to a specific level, which can be measured to determine if the button is pressed. The effect is momentary, and the voltage drops to 0V or high impedance when the button is released. A pull-down resistance of 10-100kOhm at the acquisition unit input is recommended to detect the released state.
• Green LED Indicator: The LED lights up when the button is pressed and turns off when released, providing clear user feedback.
• 0-10V Analog Output: Ensures compatibility with various building control systems, making integration straightforward.
• Electro-Mechanical Switch: Debounce time of 50ms is recommended to prevent false readings. A low pass filter is suggested to counteract impedance-caused ringing.
• Reliable Detection Levels: Button detection levels are separated by 1V with a tolerance of +/-0.5V. Releasing the button will open the circuit, and with adequate pull-down termination, the open circuit level drops to 0V, indicating no button is pressed.

Technical Specifications:

• Power Supply: 12-24V DC, 10mA
• Connections: 3 Wire Screw Terminal

The NS210 is designed to provide precise and reliable control in various applications, ensuring a seamless user experience and efficient building management. Ideal for environments requiring precise single-button control, the NS210 is a robust solution for modern building control systems.
