32 digital outputs 24V/0.5 A
6ES5 451-4UA12
The chromatograph already has internal digital
outputs on its terminal board. The
SIMATIC
digital
outputs commence with the number 33. In the ad-
jacent Fig., Output 1 means the first output on this
module.
Green lamps indicate when an output is switched on.
Connection of valves
Connect one line directly to the front plug of the digital
output module, and the return line to the central ground
terminal block.
CAUTION with classified valves
A fuse is required in the positive line. Refer
to the conformity certificate of the valve.
Short-circuit/alarm
All outputs are electrically protected against short-cir-
cuits. A red lamp lights up if an output is short-cir-
cuited, and the module outputs an alarm. This alarm
can generate the signal Device failure in the chromato-
graph (see register Operation with keyboard and
screen: Status).
Technical data
If you require detailed technical data, refer to e.g. Cata-
log ST 54.1 SIMATIC S5.
Permissible current 5 mA to 0.5 A
Residual current with OFF < 0.5 mA
Residual voltage with OFF < 3 V
Voltage with ON > U
24
- 1.5 V
Permissible cable length < 400 m
Slots required 1
Do not connect
digital outputs in parallel!
Digital outputs must not be connected in parallel if you
wish to switch valves which require more than 0.5 A.
A more powerful module must be used.
