Modbus Voice Alert


Voice Alert Module is a unique and an innovative product which can generate pre-recorded voice alerts based on the commands on Modbus TCP/IP network. In the industry generally hooters/buzzers are used to alert the users in case of alarms. In such scenario the users understand that it is an emergency but they have to go through the SCADA or HMI to understand the alarms and this causes time delay. With our Voice Alert module user can instantly get to know the alarm information through the pre-recorded voice messages and save time and be well equipped to handle the situation.
