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.

Field Wiring
Connections are made to two male 24–pin connectors (Fujitsu FCN–365P024–AU) on the front of the module. Inputs are
arranged in four groups of eight. Each group has its own common connection. Within each group, four points attach to
the A half of the connector and four points attach to the B half of the connector, as shown below.

IC694MDL654: TTL Wiring
Conventional TTL wiring practices should be followed when installing
module IC694MDL654. For noise immunity, I/O control lines connected to
the module must be less than 30 meters in length (signal attenuation limits
wiring length to less than this maximum).To be compatible with TTL
outputs, the negative logic configuration should be used as shown at right.
Wiring from each module connector to
field devices is made through a cable.
Prewired cables are available, or custom
cables can be used. Input devices can
be wired directly to the cables, or to
intermediate Terminal Blocks,
IC693ACC337, as shown here. Please
see Appendix B of the PACSystems
RX3i System Manual, GFK-2314, for
information about prewired cables,
custom cables, and Terminal Block
IC693ACC337.
