BL20-E-8AI-U/I-4PT/NI中文资料图尔克数据手册PDF规格书

■ Fieldbus-independent

■ Electronics and connection technology in

one housing

■ Connectivity: Push-in terminals

■ Protection class IP20

■ LEDs indicate status and diagnostic

■ Electronics galvanically separated from the

field level via optocouplers

■ 8 analog 2-wire inputs U/I

■ Passive input - External supply

■ 0 … 20 mA, 4 … 20 mA, -10 … +10 VDC

or 0 … +10 VDC, selectable per channel

■ Alternatively: 4PT/NI inputs (always 2 analog inputs are combined to a PT/Ni 2/3-

wire input)

Functional principle

Electronics and connection technology are integrated in the housing. A base module is not

needed. Economy modules and modules with

separate electronics and connection technology can be fitted into a station, provided the

base modules feature tension spring connections.

The use of gateways makes economy modules completely independent from the higher

level fieldbus.
