RS485 EC3 Gas Multi Sensor

Description

Datasheet

Overview

The NS312 EC3 Gas Multi sensor is an advanced low voltage multi gas sensor. It features up to 3 installed solid polymer electrode gas sensor modules. Connect the sensor output signal to an RS485 transceiver of a controller, gateway, or data acquisition unit. Or provision for an existing Wi-Fi network for wireless connectivity.

Operation

The NS312 continuously gathers data from its environment, processes it, and transmits it via wired or wireless communication channels. This multifaceted functionality enables a wide range of applications in building automation, environmental monitoring, and occupancy management. Several gas modules are available.

Gases:

• VOC-10:    VOC 10ppm
• VOC-200:  VOC 200ppm
• O3-5:        Ozone 5ppm
• HCHO-5:   Formaldehyde 5ppm
• ASH3-1:     Arsine 1ppm
• CO-1000:  Carbon Monoxide 1000ppm
• H2S-100:   Hydrogen Sulfide 100ppm
• O2-25:      Oxygen 25%
• NO2-100:  Nitrogen Dioxide 100ppm
• NH3-100:  Ammonia 100ppm
• PH3-20:    Phosphine 20ppm
• H2-1000:  Hydrogen 1000ppm

Data Communication and Control:

• RS485 Digital Output: The sensor transmits data via an RS485 interface, allowing for wired integration with building management systems (BMS), controllers, gateways, or data acquisition units.
• Wi-Fi Connectivity: The sensor supports Wi-Fi connectivity, enabling wireless data transmission via HTTPS or MQTT protocols. This allows for remote monitoring and control over a network.
• 0-10V Programmable Input/Output: The sensor features a 0-10V programmable input/output, enabling it to control external devices or receive analog signals from other sensors.
• 12V DC Output: The device provides a 12V DC output, that can be used to power other low voltage devices.

Power Supply:

• The sensor operates on a 5-60V DC power supply, providing flexibility for various installation environments.
• 4 wire screw terminals provide the electrical connections.
