Details

HD-WAMZ series products are intelligent devices mainly used for real-time monitoring of the number of lightning strikes and the number of remote signaling switches. They are divided into transmitter module HD-WAM-TZ and receiving module HD-WAM-RZ, they both realize data transmission by wireless technology.It is generally required to use in pairs.

HD-WAM-TZ transmitter module is installed next to the SPD and is used to monitor the lightning strike frequency and the change of the remote signaling switch in real time. When a lightning strike occurs, the module can record and display the number of lightning strikes. When the lightning arrester fails, the module displays “OFF”. If the transmitting module and the receiving module are paired, each transmitting module can be coded into a different address identification code. When the number of lightning strikes or the amount of remote signaling changes, the transmitting module can send the address code, the number of lightning strikes and the remote signaling switch signal to the receiving module in a wireless form.

HD-WAM-RZ receiving module is usually installed in the monitoring room, security room or duty room, etc. A receiver module can monitor up to 255 transmitter modules at the same time. The module is equipped with a 2.7-inch color LCD module that can display the number of lightning strikes and the status of the remote signaling switch of each transmitter module in real time. If the change in the number of lightning strikes is received, the number of lightning strikes of the corresponding module will be updated, and a brief prompting sound is issued at the same time. If a remote signal is received, the remote signaling indicator of the corresponding module will change from green to red, and an alarm sound will be issued continuously until the damaged SPD is replaced. The receiving module is also equipped with a data remote transmission interface, which can connect multiple receiving modules through the 485 bus, and send all the data further to the online monitoring real-time software or server to achieve local single collection , partition receiving, and overall centralized management.
