I/O Connections
Connect inputs and outputs as shown in your job prints. SC-ION board inputs are always
117VAC. Outputs may be configured (in specific groups) to provide either a path to ground or
current 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, accessed through iView, System I/O screen, 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, the iView PC must be connected through a serial cable to the board serial port.
