Maintenance
No periodic maintenance or calibration is required for this
module. If a module is to be replaced, verify the replacement
module’s relay form configuration matches the original relay
output module.
Fuses for each output are located inside the module. These
fuses are for protection of the I/O chassis connectors and
module circuit board only, and are not field-replaceable.
Should an internal fuse blow, it indicates that the module is
being used for output loads in excess of the safe rating of the
module and the I/O chassis.
Modules with blown fuses should be returned to ICS for repair
or replacement.
Safety Considerations
The relay output modules are TÜV certified as non-
interfering, and can be used in a safety system for simplex
non-safety critical outputs. For safety critical outputs,
guarded output modules should be used (model T3481, T3484,
T3485 or T3488 are recommended).
