Parker Hannifin vm24 manual T E Outputs are not short-circuit protected Environmental

Undervoltage

Protection......... The under-voltage lockout circuit is meant to

prevent the output driver from sinking or sourcing unless the user-supplied voltage Vo is between 5VDC and 24VDC.

Thermal Shutdown .... The thermal shutdown protection is intended to

protect the device from marginal environmental factors. It must not be considered short circuit protection. The thermal resistance between the FET junction and the thermal protection circuit on the SIM cards is great enough that the rapid rise in junction temperature caused by a short circuit will not transfer fast enough to protect the device from damage.

+5V Output ............. Supplied by the 6000 Series Controller/Indexer

through the 50-pin ribbon cable to connector J4. Accessed on the VM24 through the screw terminals (J5). Refer to the User/Installation Guide for the 6000 Series Controller/Indexer being used for the load limit of its +5V Output. Subtract any loads being drawn from the +5V Output at the 6000 Series unit level. The VM24 draws 0.25mA per active output and 0.5mA per active input from the +5V supply. Use this information to calculate the load limit available for the +5V Output on the screw terminal of the VM24.
