I/O Module Components
A PointScan/300 Series I/O module consists of a base assembly and a removable logic module.
All base assemblies have a hinged door that is accessible when the logic module is removed. In 4-20 mA
analog input modules (PointScan/301, /302, and /304) the hinged door provides access to jumpers and/or
100 ohm replaceable shunts.
A logic module may be removed by lightly squeezing the top and bottom locking tabs and pulling the logic
module straight out. To reinstall, insert the logic module into the base and press firmly until it snaps into
place. The logic module is fully seated when the innermost row of ventilation slots are just covered by the
top surface of the base cover.
