■ Independent of the fieldbus and connection

technology used

■ Protection class IP67

■ LEDs indicate status and diagnostic

■ Electronics galvanically separated from the

field level via optocouplers

■ 4 digital inputs, 24 VDC

■ NPN switching

Functional principle

BL67 electronic modules are plugged on the

purely passive base modules which in turn are

connected to the 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.
