■ Independent of the fieldbus and connection

technology used

■ Protection class IP67

■ LEDs for status display

■ Electronics galvanically separated from the

field level via optocouplers

■ 8 isolated relay outputs

■ Potential-free electronic relay contact

(MOSFET)

■ Max. 0.1A

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.
