1. Description

 

The NEM-500 is a small high-reliability environment monitoring unit developed to provide environment/device control and remote monitoring for communications base stations, integrated equipment rooms, and out-door cabinets.

The monitoring unit monitors important environmental factors such as temperature, humidity, smog, water penetration, access control, vibration/leaning, main distribution frame (MDF), and surge protection device (SPD). When any value collected by a sensor exceeds the preset threshold, an alarm is sent through the LCD, buzzer, or system log.

The monitoring unit also provides complete device detection functions, such as switch power status detection. Through a preserved custom interface (optional), the unit can be connected to another sensor in main contact point output type.

8.)Dry contact (relay) output interfaces

 

Eight ports are available to send alarm signals to the upper-level alarm center, or to control the device’s startup/close-down.

You can customize alarm rules, and associate any alarm signal with a relay among O1 to O8. Ports O1 to O4 output switch signals;

Ports O5 to O8 control large-current devices such as fans and heaters.

 

9.)RS485/RS232/Ethernet interfaces

 

Remote Monitoring Environment / Security Monitoring System Support RS485 RS232Four ports: A is an optional Ethernet port; B and C are fixed RS485 ports; D is an RS485/RS232 multiplex port that can be set to work in either RS485 or RS232 mode. Port A, D can be switch by the system automatically.

 

Ports A and D are used to connect the remote computer or alarm center device;

Ports B and C are used to connect other RS485-interface devices, such as the switch power, air conditioners, heat exchangers, and temperature and humidity sensors. (Note: Transparent data transmission and forwarding are supported. The complete monitoring functionality is to be developed based on standard communications protocols.)
