The KL6401 LON Bus Terminal enables direct connection of LON devices. The network variables of the connected devices are available for the Bus Coupler or the higher-level bus system.
The KL9540 system terminal contains an overvoltage filter for the 24 V field supply. The filter protects the Bus Terminal from line-bound surge voltages that can occur due to high-energy disturbances such as switching overvoltages at inductive consumers or lightning strikes at the supply lines.
B&R X20AT6402 The module is equipped with 6 inputs for J, K, N, S, B and R thermocouple sensors. The module has an integrated terminal temperature compensation.
X20PS9402 The supply module is used together with an X20 bus controller. It is equipped with a feed for the bus controller, the X2X Link and the internal I/O supply.
The module is a digital output module that is equipped with 4 opto-triac outputs using phase-angle control. L and N are fed to the module for zero-crossing detection.
