2.1.1.2 Description
The analog output module 750-553 creates a standardized signal of 0 – 20
mA.
mA.
The module has four output channels and enables, for example, the direct
wiring of four 2-conductor actuators to the connections AO 1 and Common
(ground) or AO 2, AO 3, AO 4 and each with Common (ground). The signals
are transmitted via AO 1, AO 2, AO 3 or AO 4.
The channels have a common ground.

Attention
All load impedances connected to the outputs of one I/O module have to be
either in the range of 0 ... 300
All load impedances connected to the outputs of one I/O module have to be
either in the range of 0 ... 300
Ω or 300 ... 600 Ω.
The load impedances are checked by the I/O module and inadmissible load
combinations will cause an error message.

The input signal is electrically isolated and will be transmitted with a
resolution of 12 bits.
