SAUTER

modu524/525+721

Type:  Controller
Description:  The modu524/525 automation stations (AS) are used to regulate, control, monitor and optimise operational installations. They are based entirely on BACnet/IP communication. A web server (modu-Web) is integrated into the AS for comprehensive operation, direct visualisation of the data points, notification and forwarding of alarms and creation of time profiles (scheduler). The moduCom communication module modu721 is used to extend the modu524 and modu525 automation stations. It is used to integrate third-party products on the automation level in operational systems such as HVAC engineering. Third-party products based on the field bus protocols for EIA-232 or EIA-485 such as Modbus/RTU, M-Bus can be integrated in the automation station. This allows for the option of BACnet/IP communication with the management level.
Connectivity:  Modbus RTU
