Functional principle

BL67 electronic modules are plugged into the

purely passive base modules which are needed for connection of field devices. The separation of connection level and electronics simplifies maintenance considerably. Flexibility is

enhanced because the user can choose between base modules with different connection

technologies.

The electronic modules are completely independent of the higher level fieldbus through

the use of gateways.

Note

The inputs and outputs of the digital combi-module are supplied via a common GND.

Therefore, we recommend not to use this

module for safety or emergency stop applications.

Otherwise, it must be ensured that VI and VO

at the gateway or power feeding module are

all-pole disabled.
