6 VM24 I/O Module
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.
NOTE: Outputs are not short-circuit protected.
