PACSystems RX3i AC voltage output module provides 32 discrete outputs in two isolated groups of 16. Each group has its own common. The outputs are positive logic or sourcing-type outputs; they switch the loads on the positive side of the power supply, and supply current to the load. Each group has electronic short circuit protection and generates a fault if any output in the group is in a short circuit condition. The module provides an ESCP failure status within a group back to the RX3i controller. In addition to this, the module provides a fault on loss of field side power within a group. Each group can be used to drive different loads. For example, one group might drive 24 VDC loads, and the other could drive 12 VDC loads. Power for the loads must be provided by the user from an isolated source.
