■ Protection class IP20

■ LEDs indicate status and diagnostic

■ Electronics galvanically separated from the

field level via optocouplers

■ 1 analog input 0/4…20 mA

Functional principle

BL20 electronic modules are plugged into the

purely passive base modules which are used

for connection of field devices. Maintenance is

significantly facilitated due to separation of the

connection level from the module electronics.

Furthermore flexibility is enhanced because

the base modules provide a choice of tension

spring or screw connection technology.

The electronic modules are completely independent of the type of higher level field bus

through the use of gateways.
