Modules are wired to I/O Terminal Blocks with the terminal styles shown below. Wiring can be
completed either before or after installing I/O modules. Refer to the individual block datasheets in
this manual for specific wiring details.
Terminal Assignments for I/O Terminal Blocks
The Terminal Block with box terminals (catalog number IC670CHS002 and 102) has 51 terminals,
each of which accommodates one AWG #14 (avg 2.1mm
2
cross section) to AWG #22 (avg
0.36mm
2
cross section) wire, or two wires up to AWG #18 (avg. 0.86mm
2
cross section). An
insulated external 5mm (0.2in) jumper such as Altech #8879 can be used to connect adjacent
points. When an external jumper is used, the wire capacity is reduced from AWG #14 (2.10mm
2
) to
AWG #16 (1.32mm
2
).
The I/O Terminal Block with barrier terminals (catalog number IC670CHS001 and 101) has 37
terminals. Each terminal can accommodate one or two wires up to AWG #14 (avg 2.1mm
2
cross
section).
The I/O Terminal Block with Connectors (catalog number IC670CHS003 and 103) has two 20-pin
male connectors for I/O wiring. The mating connector is Amp part number 178289-8. Any tin
plated contact in the AMP D-3000 series can be used with the connector (Amp part number
1-175217-5 for high contact force receptacle for 20-24 gauge (0.20-0.56mm
2
) wires), 1-175218-5
for high contact force receptacle for 16-20 gauge (0.56-1.42mm
2
)). A kit containing two mating
connector housings and contacts is available as GE Fanuc part number IC670ACC003. The kit
contains pins for 16-20 gauge wire. A crimping tool must be provided, and used according to the
guidelines in the datasheet provided with the I/O Terminal Block with Connectors.
Each terminal block has two independent sets of terminals.
