Functional principle
BL20 gateways are the head component of
a BL20 station. They are designed to interface the modular fieldbus nodes to the higher level fieldbus (PROFIBUS-DP, DeviceNet,
CANopen, Ethernet).
All BL20 electronic modules communicate
2 x end brackets BL20-WEW-35/2-SW, 1 x end plate over the internal module bus, the data of
BL20-ABPL
which is transferred to the fieldbus via the

gateway, so that all I/O modules can be configured independently of the bus system.

Power Supply
The USYS system supply feeds power to the gateway and the I/O
modules.
The UL field supply feeds power to the sensors and actuators.
