The new fieldbus systems THERMASGARD
®
911 with S-Bus or Modbus protocol (selectable at the device) help to save time and money
due to less time expenditure for cabling and installation. Extensions or modifications are easy to carry out, providing for guaranteed flex-
ibility and future. These fieldbus devices can be mounted on top hat rails and are easy to operate.
THERMASGARD

9111 fieldbus input modules can convert active signals or passive sensors into S-Bus or Modbus protocols that can be
processed by corresponding devices.

9112 fieldbus output modules can convert S-Bus or Modbus protocols into digital or relay outputs that can be proc-
essed by corresponding devices. Modules providing a manual operation option allow switching individual outputs on and off to facilitate
localisation of faults.
