1.Overview

This is a small high-reliability environment monitoring unit developed to provide environment/device control
The monitoring unit monitors important environmental factors such as temperature, humidity, smog, water penetration,
collected by a sensor exceeds the preset threshold, an alarm is sent through the LCD, buzzer, or system log.
Through a preserved custom interface (optional), the unit can be connected to another sensor in main contact point
 

2.Features

W-TEL monitoring unit is designed for the outdoor cabinet application. It height is 1U*2U and suitable for standard **-inch rack mounting. Front cabling, friendly installation, greatly facilitating testing, field commissioning and remote monitoring to all sensors for customers.

2>*-channel temperature detection can sense temperatures of the main equipment cabin and battery cabin respectively

4>Optional Chinese/English display module facilitates parameter checking and setting on site

6>With operating indicator, alarm indicator, and buzzer

8>Setting the LED in the cabinet to on/off when opening/closing the door through the access control function

*0>The main equipment offers standard isolated RS**2/RS**5/RS**2 communication interfaces for direct connection to wired or wireless MODEM, and supports Ethernet, optical fiber, E1 and other interfaces via optional conversion interfaces
