BL20-2AIH-I-10中文资料图尔克数据手册PDF规格书

■ Fieldbus and connection technology independent

■ Protection class IP20

■ LEDs indicate status and diagnostic

■ Electronics galvanically separated from the

field level via optocouplers

■ 2 analog inputs 0/4…20 mA

■ HART

Functional principle

BL20 electronic modules are plugged into the

purely passive base modules which are used

for connection of field devices. The separation

of connection level and electronics simplifies

maintenance considerably. 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 higher-level fieldbus through

the use of gateways.

Note

This module is a customer-specific variant

and not compatible with the standard module. The standard HART input module is the

BL20-2AIH-I (6827331).
