IC693PIF301/400 Personal Computer Interface (PCIF) Cards
These two Personal Computer Interface cards (PCIF and PCIF2) provide an alternative method of
controlling Series 90-30 I/O. Either card can be used in place of a Series 90-30 PLC CPU. These
ISA-compatible cards can be installed in any IBM-PC/AT ISA bus computer. The cards are
implemented using computer language software (for example, C), or PC control software.

Figure 11-6. Example of PCIF Interface to Series 90-30 I/O
Both of these PCIF cards have a 25-pin I/O expansion connector that connects to standard Series
90-30 Expansion and Remote baseplates (see the “Baseplates” chapter) via I/O expansion cabling.
Remote racks can be located up to 700 feet ( 213 meters) and Expansion racks up to 50 feet (15
meters) from the personal computer. Several standard prewired I/O expansion cables are available
from
GE. Alternately, custom length cables can be built. Please refer to the “Cables”
chapter of this manual for information on standard and custom I/O expansion cables.
These cards also provide connections to an internal watchdog-supervised RUN output relay
contact. This contact is closed under normal operating conditions, but opens if the computer or
software application fails, which makes it useful for interfacing with external safety circuits.
