Individual opto-couplers for each channel provide isolation for
the Model IOS-440. Channels are isolated from each other in
groups of 8. There are 8 channels to a group or port. Because
the input lines of a single port share a common connection, the
individual inputs are not isolated from each other within the same
port. However, separate port commons are provided to facilitate
port-to-port isolation.
Input opto-couplers of this device are bipolar and accept
voltages (16-40V) DC or AC peak. The opto-couplers connect
to an FPGA that provides the I/O read/write functionality, interrupt
handling, and debounce control.
5.0 SERVICE AND REPAIR
SERVICE AND REPAIR ASSISTANCE
Surface-Mounted Technology (SMT) boards are generally
difficult to repair. It is highly recommended that a non-functioning
board be returned to Acromag for repair. The board can be
damaged unless special SMT repair and service tools are used.
Further, Acromag has automated test equipment that thoroughly
checks the performance of each board. When a board is first
produced and when any repair is made, it is tested, placed in a
burn-in room at elevated temperature, and retested before
shipment.
Please refer to Acromag's Service Policy Bulletin or contact
Acromag for complete details on how to obtain parts and repair.
PRELIMINARY SERVICE PROCEDURE
Before beginning repair, be sure that all of the procedures in
Section 2, Preparation For Use, have been followed. Also, refer
to the documentation of your carrier board to verify that it is
correctly configured. Verify that there are no blown fuses.
Replacement of the carrier and/or IOS with one that is known to
work correctly is a good technique to isolate a faulty board.
CAUTION: POWER MUST BE TURNED OFF BEFORE
REMOVING OR INSERTING BOARDS
