1、High Temperature Resistance: This network controller is high temperature resistant and can work in an environment of -40 degrees to +85 degrees. 2、Normally Closed Output: 2 channel IP network relay normally closed output (no normally open output), the output does not carry voltage or current. 3、Featured Function: The relay will actively PING the set IP. When the PING fails, the relay will be disconnected for 10 seconds and then closed (this function is used to restart network devices, such as routers). 4、Maximum Load Can be Connected: The network controller with chip and program upgrade can be connected to the maximum load, DC 5A, AC 10A, maximum voltage 250V. 5、Application: This is a network controller that can be used to monitor whether routers or other network devices are disconnected. 1 x Network Watchdog Item Type: IP Network Relay ModuleModel: HHT-NET2DPower Supply Voltage: DC12VIndustrial Grade Working Environment: -40 to +85 Degrees.The Maximum Load That Can be Connected: DC 5A, AC 10A, Maximum Voltage 250V.(Chip and Program Upgrade) Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
