Parameters Of Digital Output Modules - Siemens SIMATIC Manual

Digital modules
3.24 Digital output module SM 322; DO 16 x DC 24 V/0.5 A: (6ES7322-8BH10-0AB0)
Load resistances of the actuators
The load resistances of the actuators must be in the range from 48 Ω to 4 Ω. For larger
values, a suitable resistance must be switched directly on the connection clamps of the
actuator (observe the maximum power loss with signal "1").
The permissible rated voltage of the actuator must be greater than 28.2 V.
The lower response threshold of the actuator must be known in the operating temperature
range or be determined experimentally. The output voltage of the module with signal "0" can
be influenced through parallel switching of a resistance directly on the actuator connection
clamps. With the selection of the resistance, the maximum power loss with signal "1" must
be observed.
● Load resistances between 10 kΩ and 1 MΩ can be reported as short-circuits after L+.
● Unwired outputs or loads greater than 1 MΩ are reporeted as "wire-break".
