SB1 installation examples
Easy to operate with the frontpanel

The SB1 controller can be operated in an easy way from the frontpanel. The controller is also fitted with a service port for quick and easy configuration with a laptop/desktop.

MODBUS RTU RS-485 communication with host

The SB1 temperature controller is fitted with a MODBUS RTU RS-485 interface as standard. With this the heat-tracing can be remotely monitored and operated from the central control room of the plant. A power optimization algorithm reduces peak power by synchronizing the SB1 modules together.


With the COM K2 you can connect you controller to an USB port of your laptop/desktop. With this  the controller can be configured quickly and easy.
