The AC-460 and AC-460E 16-bit I/O expansion units increase input/output capacity for the AC-600 Threshold terminal controller. This expansion unit shares the intelligence of the terminal controller's memory and uses the same supervision scheme. The AC-460 adds 14 inputs and 14 outputs to the two inputs and two outputs provided on every terminal controller. The AC-460E allows for 30 outputs for point control or elevator floor selection.
Key features of the AC-460/460E I/O Expansion Unit include:
- Additional outputs: standard SPDT dry contact relays
- Units can be mounted inside terminal controller enclosure
- Inputs and outputs can be linked through terminal controller configurations
- Linked relationships are local to terminal controller enclosure
- Linked relationships maintained in the event of loss of network communications
