The AI/DI input channel can detect signals from multiple types of sensors, including
4–20 mA sensors, negative temperature coefficient (NTC) resistor-based temperature
sensors, current-based sensors, and devices with dry contacts.
The ECC500 supports the automatic assess of sensors such as water sensors and NTC
resistor-based temperature sensors, simplifying delivery and deployment.
The ECC500 provides the 12 V DC power supply to devices such as sensors and audible
and visual alarms. Additional power supply to these devices is not needed.
All boards, cards, and sensors are hot-swappable.
The ECC500 supports fault isolation. If a port is short-circuited or damaged, it is isolated
to ensure that other ports and boards are not affected.
The ECC500 features flexible extensibility. Boards or modules can be added or removed
to meet requirements of different scenarios.
The ECC500 can be mounted on a rack or wall.
Software Functions
You can use a web browser to access the ECC500 for remote management.
You can upgrade the system, main control module, and other functional modules
remotely. The main control module rolls back to the source version if the upgrade fails.
You can re-upgrade functional modules if upgrades fail.
The ECC500 supports simple network management protocol (SNMP) northbound
interfaces that are compliant with SNMP v1, v2c, and v3.
The ECC500 allows you to download the management information base (MIB) files.
The ECC500 allows you to download or upload configuration files for system backup.
The ECC500 allows you to manage users and alarms. You can also download log files.
The ECC500 provides user-friendly interfaces, including the web user interface (WebUI)
and LCD user interface (LUI). You can remotely and locally maintain the ECC500 over
the WebUI and LUI respectively.
The ECC500 can automatically identify boards, cards, and sensor devices.
RS485 ports of the ECC500 support the transparent transmission mode, ensuring
real-time communication between the southbound equipment and the NMS.
The ECC500 locates abnormal sensor connections based on alarms, thereby facilitating
maintenance.
Northbound interface: connects to the upper-layer NMS or equipment for provisioning services and
reporting alarms and performance data.
Southbound interface: connects to the lower-layer NMS or equipment for provisioning services and
transmitting performance indicator data.

Transparent Data Transmission
If the ECC500 is used for transparent data transmission, the NMS such as the NetEco or
third-party NMS must be configured and the ECC500 works only as a data collector. The
ECC500 reports collected data to the NMS, where users manage devices.
Figure 2-2 shows the networking for transparent data transmission.

The ECC500 provides SNMP northbound interfaces for connecting to a third-party NMS to query
data and report alarms.
The ECC500 used for transparent data transmission can connect to diverse devices complying with
the Modbus protocol and providing dry contacts. For the devices that can be connected, see the
monitoring device list for the project.
Local Management
If the ECC500 is used for local management, there is no need to configure the NMS and the
ECC500 works as a data collector and manager. The ECC500 collects, analyzes, and
processes device data, while users manage the devices on the ECC500 WebUI.
Figure 2-3 shows the networking for local management.
