1. The external voltage supply must be capable of buffering brief mains failures of 20 ms as specified in EN 60204-1. Suitable power supplies are available as
accessories from Rockwell Automation.
2. Within the limits of U
V
.
3. As per IEC 61131-2.
4. Applies to the voltage range between –30V and +30V.
5. As per IEC 61131-2.
6. On the device plug.
7. In the case of a fault (0-V cable open circuit) the max. leakage current flows in the OSSD cable. The downstream controller must detect this status as
LOW. A FPLC (Fail-safe Programmable Logic Controller) must be able to identify this status.
8. The maximum rated load inductance is higher with lower switching sequence.
9. When active, the outputs are tested cyclically (brief LOW). When selecting the downstream controllers, make sure that the test pulses do not result in
deactivation when using the above parameters.
10. 0 Make sure to limit the individual line core resistance to the downstream controller to this value to ensure that a short-circuit between the outputs is
safely detected. (Also note EN 60204 Electrical Machine Equipment, Part 1: General Requirements.)
11. 1) As per IEC 61131-2.
12. 2) Applies to the voltage range between –30V and +30V.
13. Depending on load, power supply and wire cross-section. The technical specifications must be observed.
