2.1.1.2 Description
The analog output module 750-585 creates intrinsically safe standardized
signals of 0-20 mA in the hazardous area of Zone 1.
The installation of the WAGO-I/O-SYSTEM 750 is to be done in zone 2 or in
non-hazardous environments.
The module has two output channels and enables, for example, the direct
wiring of two 2-conductor actuators to the connections AO 1 and 0V or AO 2
and 0V. The intrinsically safe signals are transmitted via AO 1 or AO 2.
The input channels of a module have a common ground and a shield (screen)
connection (S). The Shield (screen) is directly connected to the DIN rail. A
capacitive connection is made automatically when snapped onto the DIN rail.
The Output signal of each channel is electrically isolated and will be
transmitted with a resolution of 12 bits.
The operational readiness and trouble-free internal data bus communication of
the channels are indicated via a green Function LED.
