PACSystems RX3i 32-Point Positive/Negative Logic input modules provide 32
positive or negative logic input points in four isolated groups of eight. Each group is
referenced to its own common connection.

5/12VDC (TTL) 32 Point Positive/Negative Logic Input module, IC694MDL654,
shown at left, provides 32 discrete TTL voltage threshold input points that operate
at levels up to 15V. A single, regulated +5V supply (current limited to approximately
150mA) is available through the I/O connectors on the front of the module. This
supply is generated on the module and is isolated from the backplane. Its power
input comes from the +5V logic supply on the PLC backplane. By installing jumpers
on the I/O connector, you can choose to power the inputs from this internal supply
instead of powering them with an external user provided supply.

24VDC 32 Point Positive/Negative Logic Input module, IC694MDL655, provides

1-16

32 discrete input points that operate at levels up to 30V. Power to operate field
devices can come from an external supply or from the module’s isolated +24 VDC
output.

48VDC 32 Point Positive/Negative Logic Input module, IC694MDL658, provides
32 discrete input points that operate at levels up to 60V. Power to operate field
devices must be provided using an external supply.

The blue band on the front label indicates a low-voltage module.
These modules do not report special fault or alarm diagnostics. Green LEDs

indicate the ON/OFF status of each input point.
These modules can be installed in any I/O slot in the RX3i system.

Installation in Hazardous Locations
