NetIOX
The NetIOX is a slave board of the NetNX cluster controller. It facilitates full control of two doors or gates, using two relays per door and inputs for door position and RTE.
The NetIOX is daisy chained to other NetIOX units and to the NetNX using four wires only.
It can use the backup battery connected to the NetNX for uninterruptible operation during power outage. |
