I/O Connections
Connect inputs and outputs as shown in your job prints. SC-ION board inputs are 115Vac +/-
15%. Outputs may be configured (in specific groups) to provide either a path to ground or cur-
rent to drive indicator lamps/LEDs.
Output State Selection The outputs are divided into three groups. Each group shares
a common. The common may be wired to provide a current source or a path to ground. The
groups are:
•Relays 1 — 4
•Relays 5 — 8
•Relays 9 — 16
The commons for the groups are determined by the connections made to board connector J4.
The appropriate connections are determined during the job survey. Each system is configured
before shipment. You need only connect the inputs and outputs as shown on the job prints.
Board Addresses Each of the 16 inputs and 16 outputs on the board has an address on
the system bus. The addresses are assigned as indicated by the job survey before the system is
shipped. A software tool, running on a Windows platform, is used to set individual addresses
and also to set the address range (10-488 or 10-988) used for the job. To configure the board, a
Windows PC running the software tool must be connected to the board serial port.
Board Programming
Addresses are programmed for each SC-ION
board input and output at the factory using a tool
called SCION Configuration.exe. You should
never have to use this tool without factory techni-
cal support. A typical programming screen from
SCION Configuration is shown for informational
purposes:
