The HD Pulse Module is perfect for bringing large banks of pulse submeters into Modbus networks. Connect up to 23 dry contact pulse outputs for easy Modbus RS-485 integration. The High Density Pulse Module (A8911) provides a convenient way to add multiple pulse output devices to Modbus systems such as the Energy Monitoring Hub. The A8911 accepts up to 23 standard pulse sensors and can function as a slave device with any Modbus master. This data can easily be integrated to a network of other critical energy sensors such as Modbus power meters to provide a comprehensive energy monitoring solution.
