Display Elements - WAGO 750 Series Manual

14 • 750-479/000-001 [2 AI DC ±10 V Differential Measurement Input/Sync]

Display Elements

The operational readiness and trouble-free internal data bus communication of
the channels are indicated via a green Function LED. Overrange or underflow
of the measuring range is indicated via a red error LED.
Any configuration of the input modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
The voltage supply is done via system voltage.
Attention
This module has no power contacts. For field supply to downstream I/O
modules, a supply module will be needed.
The analog input module 750-479/000-001 can be used with all
couplers/controllers of the WAGO-I/O-SYSTEM 750 (except for the economy
types 750-320, -323, -324 and -327).
